a jet flies with wind at 1100 km/h and against the same wind at 750 km/h.Find the rate of the wind and the speed of the jet in still air.

Answer 1

Let y = wind speed and x = plane speed

x + y = 1100
x - y = 750

Add the two equations.

2x = 1850

x = ?

Solve for x. Insert value into one equation to find y. To check, insert both values into other equation.

Answer 2

x=925
