How fast is 9 miles per second in miles per hour?
There are 3600 seconds in an hour (60 minutes * 60 seconds). 9 miles per second is 9 * 3600/hr or 32,400 mph. the * means multiply and the / mean per
How fast is this in miles per hour (miles/hr)?
You have to be careful with the units. The speed of light is 3.00 * 10^8 meters per second (m/s). There are 1610 meters per mile (m/mile). There are 3600 seconds per hour (s/hr). (m/s * s/hr) / (m/mile) = m/hr * miles/m = miles/hr (You can treat the units just like variables, multiplying and dividing fractions and canceling units that appear in both numerator and denominator. That also shows you how the numbers should be treated.) So it's (3.00 * 10^8 m/s * 3600 s/hr) / (1610 m/mile) = (3.00 * 3.600 / 1.610) * 10^8 = 6.708 * 10*8 miles/hr
How fast is this in miles per hour?
so he ran it 100 meters/9.77 seconds Multiply by 1 mile/1609 meters (which is basically like multiplying by one, since 1mile = 1609 meters, so you have something divided by the same thing, which is 1) but look what happens to the units! 100 meters * 1 miles ---------------- -------------- 9.77 seconds 1609 meters the meters cancel because of cross multiplication, leaving miles 100/1609=.06215 so now we have .06215 miles/9.77 seconds =0.00636 miles/second now using 3600 seconds in an hour, we make the seconds cancel .00636 miles/second * 3600 seconds/1 hour if you write that out on paper you see you're left now with miles/hour, and .00636*3600 22.89 mph
How fast would 5 Miles Per Second be in MPH?
Firstly convert second to hour(H). 1 Second=1/3600 hour Now put it in place of seconds-------> 5 miles per second= 5 miles per (1/3600) Hour = 5*3600 miles per hour = 1800 MPH
100 meters in 9.69 seconds is how many miles per hour?
I set these problems up like this: Put your answer in the correct units on the left, then an equal sign, then what the problem gives you on the right. ? mi / ? hr = 100 m / 9.69 s Then multiply all your unit conversions continuing on the right. I first want to convert meters into miles. I want meters to go away and miles to be on the top (which is in line with miles in the answer). In order to cancel meters, I'll put meters in the denominator. Units will only cancel if one is on top and one is on bottom. 1 mile = 1609 meters. ? mi / ? hr = (100 m / 9.69 s) * (1 mi / 1609 m) Ok, so we have miles on the top which is what our answer is, so we're good on the top. Now, we want hours on the bottom, but the problem gave us seconds on the bottom. I know 60 seconds in a minute and 60 minutes in an hour. Be sure to cancel out seconds and minutes to leave hours on bottom ? mi / ? hr = (100 m / 9.69 s) * (1 mi / 1609 m) * (60 s / 1 min) * (60 min / 1 hr) Great, we have hours on bottom. Now multiply what is on top and divide what is on bottom, like this. Enter into your calculator: 100 * 1 * 60 * 60 / 9.69 / 1609 / 1 / 1 = 23.09 That's our answer. 23.09 mi / hr, which is 23.09 miles per hour.
This is my first answer on quota so pls give suggestions!“How fast” would depend solely on what distance you can maintain a speed of 11 miles per hour for. For a sprint, that would be quite a bit below the “average”, but for endurance based races, that speed would be pretty impressive. At 11 mph, here are the times for various track distances:100m- 20.33 seconds200m- 40.67 seconds400m- 1 minute 21 seconds800m- 2 minutes 43 secondsmile- 5 minutes 27 seconds5k- 16:555 mile- 27:1610k- 33:49half marathon- 1:11:27marathon- 2:22:55Running 11 mph for the duration of a marathon would put you within 20 minutes of the world record, held by Dennis Kimetto at 2:02:57. Any distance under 400m would probably begin to be below average, however the average itself is hard to calculate, as most of the results of 13 year olds we see are those that train for this, not your typical teenager.This is where I got the numbers: Running speed and pace chart conversion
If the speed of sound is 770 miles per hour, how is it possible that were able to hear sound for miles away the second the sound occurs?We’re not able to hear sound “the second [it] occurs” unless the source of the sound is very close.There are lots of times when you can tell that the sound takes a significant period of time to get to you. The most obvious is thunder and lightning — the flash of lightning and the clap of thunder are generated at the same time, but you don’t hear the thunder until many seconds later.Back in the 1960s I went to see the launch of one of the Apollo missions to the Moon (can’t remember exactly which one). The launch viewing area was about 6 miles from the launch pad. We saw the rocket engines light and the Saturn V lift off the pad in complete silence. Then about 25 seconds later the silence was shattered when the BOOM hit us. That’s how long it took the sound to get to us from the launch pad.Along those same lines, in 1972 my dad and I were watching the Apollo 17 launch from our house near Orlando, 60 miles from the space center. We’d never been able to hear anything from our house during a launch, so we weren’t expecting anything this time either. However, the launch was late at night, when everything was still and quiet. About 5 minutes after launch, when the rocket itself was just a speck of light in the distance, we heard a distant rumble and realized we were hearing the launch from 5 minutes ago!There are lots of other examples, but if you just pay attention to the world around you, it’s easy to see that sound clearly takes time to get to you. Sounds travels about 2/10ths of a mile per second, so unless you’re within 2/10ths of a mile, you don’t hear sound “the second it occurs.”
If you can hold it for a mile, you can run a 3:32 mile. That pace has you running a 13.3 second 100m and a 53 second 400m. If you can hold it for a marathon (42,2km), you can run a 1hr 26 min marathon. The mile, 1/4mile, and 100m times are all impressively fast and physiologically possible. The marathon time is completely unrealistic. I would say 17 miles per hour is very fast (way above average) for any age group.
Speed of sound travels at 1,136.9 feet per second. how fast is that in miles per hour?
1,136.9 feet per second * 60 seconds = 68,214 feet per minute 68,214 feet per minute * 60 minutes = 4,092,840 feet per hour 4,092,840 feet per hour / 5,280 feet in a mile = 775.16 miles per hour
You asked how many miles is light speed, but those have completely different units. If you’re asking how many miles per second light travels, it’s 186,282 miles per second.So every second, light (let’s say a photon) travels 186,282 miles. That’s a big distance.
