# How fast does jet travel?

What is the rate of the wind, If the jet travels 9180 mi in 9 hours with the wind

but 1860 mi in 3 hours against it?

Let J = rate of jet in still air

W = rate of wind

Distance formula is  d = rt   so   r = d/t

J = (620+1020)/2 = 820 mph

J - W = 620

820 - W = 620

W = 820 - 620 = 200 mph
