SOLUTION: An airplane can travel 380 mph in still air. If it travels 3699 miles with the wind in the same length of time it travels 3141 against the wind, what is the speed of the wind?

Question 627238: An airplane can travel 380 mph in still air. If it travels 3699 miles with the wind in the same length of time it travels 3141 against the wind, what is the speed of the wind?
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
The wind is moving air from an area of high pressure to an area of low pressure. The speed at which the wind moves relative to the ground is wind speed.

In equation form, speed is:

if the time when airplane travels with the wind is and the time when airplane travels against the wind is , we are given that ...we will use
so, if it travels miles with the wind and has a speed of , we have
....now calculate the time

.....now we know the time and we can plug it in formula for speed against wind where using same time

.........your answer
