What is the speed of a plane that travels at a rate of 530 mph with a wind of r mph?
Answer is E not enough information. Is the wind a head wind or a tail wind? The wind is either pushing the plane faster (tail wind) so 530+r or the wind is pushing against the plane (head wind) so 530 -r. Actually the math doesn't work out exactly like that, but given your choices.
What is the speed of a plane that travels at a rate of 460 mph against a wind of r mph?
What is the speed of a plane that travels at a rate of 460 mph against a wind of r mph? Choose the correct speed. A. 460/r mph B. r-460mph C. 460 + r mph D. 460 – r mph Is it A? Thanks in advance!
What is the speed of a plane that travels at a rate of 470mph with a wind of r mph?
You would represent that plane's air speed at 470 + r (with the wind) The speed of the plane going against the wind would be 470 - r When you can find out air speed, you replace "r" with that speed and then you can find sum (or difference) of the two. Note, actually the plane will always be going 470, but relative to ground, it will be "r" less, or "r" more fast because of additional push forward (or pull back) due to speed of air that the plane is sort of being buoyed up inside above the ground. Next question? Thanks for two pts.
What is the speed of a plane the travels at a rate of 440 mph against a wind of r mph?
It depends on how you are measuring the speed of the airplane. Are you using a pitot tube, a sat/nav system or something else like radar. With a pitot tube you would need to subract the head wind. If you are using a sat/nav then the wind speed is not a factor.
A plane travels at a rate of 400 mph in calm air.?
The speeds against and with the wind are in the ratio of 700 : 900. The average of the two speeds is the speed in still air, which is 400 mph. We get this average if the two speeds is 350 : 450 = 400-50 : 400+50. So the wind is 50 mph.

1. An airplane travels at a constant rate. Flying with the wind, it takes 3.3 hours to travel 1980 miles. Flying against the wind, the return trip takes 5 hours. If there was no wind, how fast was the airplane flying? Check your answer by verifying the distance, rate, and time formula for both directions that the airplane flies. Show work/steps please.
How do you calculate how many miles per hour an airplane travels?
I’ve read the answers posted so far and, without a ton of scrutiny, they are correct. Irrespective of the method you use, to obtain your speed, you have to firmly locate at least two points, called ‘fixes’, to establish the Great Circle distance between them. Once you have the distance, you divide that by elapsed time between the fixes to obtain your ground speed. In the old days, when flying over the ocean where no land or electronic fixes were available, a navigator would have to obtain at least three celestial (star/planet) Lines of Position (LOP’s) to obtain each position. That was a lot of work and wasn’t easy, especially in turbulence or obscured sky. Since one of those fixes could take 20 minutes and the airplane was flying 6 miles per minute, that means you were really figuring out where you were 20 minutes or 120 miles also. When flying from Phuket to Diego Garcia in the Indian Ocean, no fixes were typically available during the day and the navigator had to rely upon a Sun Line LOP to estimate position and resultant speed. This method could be pretty hairy because the next point of land after Diego Garcia was the bottom of the ocean or Antarctica.With that said, if you want to get a little depressed, calculate your speed for a domestic airline trip between two rather close airports such as Portland and Seattle. When you make your calculation, include all the time it takes from the moment you are dropped off at one airport to the moment you leave the other airport. You will find that you spend a significant amount of time combating/tolerating/gnashing your teeth over delays related to infrastructure inefficiencies such as TSA, parking, baggage claim, passenger loading, blah, blah….. For this reason, commercial aviation should probably focus more on infrastructure efficiencies rather than attempt to sequeeze another slight increase in airplane airspeed. If Amtrak ever got their act together with high speed rail, commercial airline short routes would find a real competitor.Note that when you are navigating over water, you typically measure speed in knots (nautical miles per hour) versus (statute) miles per hour. A knot, 1.15 statute miles per hour, is mathematically better suited to Mercator or Lambert Conformal nautical charts.
An airplane travels 600 miles against the wind in 5 hrs. and makes the return trip with the same wind in 2 hrs?
I think you're asking the rate of the wind? We know that D = r X t So: 600 = 5r 120 = r And 600 = 2r 300 = r Solve the system: x + wind = 300 x - wind = 120 so 2x = 420 and x = 210 so the speed is 210 and the wind is 90
