Question

An airplane travels 4374 kilometers against the wind in 6 hours and 5514 kilometers with the wind in the same amount of time. What is the rate of the plane in

still air and what is the rate of the wind?

Answer 1

air = 95 mph

plane = 824 MPH

Explanation:

6(x-y) = 4374

6(x+y)= 5514

6x - 6y = 4375

6x + 6y = 5514

12x = 9889

x = 824 mph

y = 95 mph
