A giraffe can run at a speed of 32 miles per hour. which animal listed in the chart has a speed that is 15/16 of the speed of a giraffe?
Explain your answer. Cat. 30 miles Cheetah. 70 Jackal. 35 2. Some frilled lizards grow to be 90 centimeters long. If 2/3 of this length is its tail, how long is the tail? 3. Eric has 240 coins in his collection. 11/20 of the coins are pennies. 4/20 of the coins are nickels. The rest of the coins are quarters. How much of the coins are quarters?
A giraffe can run 32 miles per hour. What is this speed in feet per second? Round your answer?
it's just a matter of converting miles to feet and hours to seconds: 32 miles/ hour = 32 (5280) ft / 60 minutes = 32(5280) ft / 60(60) seconds = 168960 ft / 3600 seconds do the division and you get: approximately 46.9 ft/sec.
A giraffe can run 32 miles per hour. What is this speed in feet per second?
I got 46.9 but i had to round it to 47 ft/sec, i had the same question in my algebra 1 workbook
If someone can run 32 cm per 1/100 second. How many km/hr can he run?
not liking some of these other answers.... 32 cm per 1/100 sec = 32m per second(100cm = 1m) 32 * 60sec * 60min = 115200m/hr 1000m = 1km = 115200/1000 = 115.2km/hr (hmm pretty dard fast as the first person pointed out, and his work turns out good afterall:P)
I need help with unit rates!?
There are 5,280 feet in 1 mile and there are 3,600 seconds in one hour. You can convert this equation by setting it up this way: ( 32miles / 1 hour ) ( 5,280 feet / 1 mile ) ( 1 hour / 3,600 seconds ) 32 x 5280 = 168, 960 168, 960 ÷ 3, 600 = 46.9 feet/sec EDIT: What I did was use conversion factors to set up what you wanted to find, which was feet per second. I made sure that the miles and hours would cancel each other out, leaving only feet and seconds. By setting it up the way I did, all you would have to do is multiply the numbers straight across then divide what ever number(s) was/were in the denominator and you'd have your answer in the appropriate units. :)
What is 32 miles per hour in feet per hour?
1 mile per hour = 5280 feet per hour. So, 32 miles per hour = 168,960 feet per hour. Hope that helped......
Using a formula, if your heart beats 72 times per minute, how many times will your heart beat in an hour? In a day?
This process is known as Dimensional analysis. This is, in my opinion, one of the most important analytical skills that the average person should master. If only because it is so useful in our everyday lives. There are a few ways that you can do this, but I prefer to let the units do the work for me.. We start with [math]\frac{72beats}{1min}[/math]. We want [math]\frac{N(number)beats}{1hour}[/math]. We'll need a conversion factor: i.e. there are 60 mins in 1 hour. So,[math]\frac{72beats}{1min}*\frac{60min}{1hour} = \frac{4,320beats}{1hour}[/math]; Note: the minute units cancel because there is an unspoken (1) in front of each ([math]\frac{1}{1}=1[/math]). But how do we know how to set up the conversion factor? It easily could have been [math]\frac{1hour}{60mins} [/math]right? If we did that, the units would be [math]\frac{beats*hour}{min^2}[/math].. that's just crazy..As for how many beats per day.. the conversion factor is:[math]\frac{ 24 hours}{1day}[/math].[math]\frac{4,320beats}{1hour}*\frac{24hours}{1day} = \frac{103,680beats}{1day}[/math]In a year.. the conversion factor is [math]\frac{365days}{year}[/math]. [math]\frac{103,680beats}{1day}*\frac{365days}{1year} = \frac{37,843,200beats}{1year}[/math]If you assume a median life expectancy of 65 years: that's [math]\frac{37,843,200beats}{1year}*\frac{65years}{1lifetime} = \frac{2,459,808,000beats}{1lifetime}[/math].. So, that's all of the beats you might get. About 2.5 billion.. Use them wisely;)**Note that the heart rate is dynamic, and really should be estimated from a weighted average over a long period of time. Thus these numbers aren't very accurate..
How would i solve this? (inter. algebra, rates/ratios&proportions)?
My teacher had me pretty stumped today :-x so i'm hoping somebody can walk me through these so I can figure out if I'm doing these right, and if not if you could so kindly point me in the right direction.. 1) Find the unit rate - Four pounds of apples costs $1.96. (here, i divided 1.96 by 4 and got $.49 per pound as my answer.) 2) Find the unit rate - Sal washed 5 cars in 50 minutes. (I divided 50 by 5 and got 10 minutes per car) ^^ to be completely honest... am I even solving for the right thing on those questions?!? :-( ^^ 3) A giraffe can run 32 miles per hour. What is this speed in feet per second? Round your answer to the nearest tenth. (Here I got really, really lost and didn't really end up with an answer that made sense. I tried dividing 32 by 60 for the minutes, and then dividing by 60 again for the seconds and ended up with 0.8 miles per second...) Thank you SO much for your kind help ahead of time! I really appreciate it!
