Question

An airplane flying into a headwind travels the 2800 mile flying distance between two cities in 4 hours and 40 minutes. On the return flight, the same distance is traveled in 4 hours. Find the air speed of the plane and the speed of the wind assuming that neither changes. Find the plane and wind speed.

I am so lost I don't even know how to set up the equations! Please help!

Answer 1

W=wind speed
A=air speed

Equation are set up using
Speed*Time = distance,
or
Distance/Speed = Time

2800/(A-W)=4 2/3 ...(1)
2800/(A+W)=4 ...(2)

Solve system of equations for A and W.
