With the tailwind a jet flew 2000 miles in 4 hours the jets return trip against the same wind required 5 hours?

To find the speed of the jet and the wind, we can use the formula: speed = distance/time. With the tailwind, the jet's effective speed was 500 miles per hour (2000 miles ÷ 4 hours), and against the wind, it was 400 miles per hour (2000 miles ÷ 5 hours). Let the jet's speed be ( j ) and the wind's speed be ( w ). We can set up the equations: ( j + w = 500 ) and ( j - w = 400 ). Solving these gives the jet's speed as 450 mph and the wind's speed as 50 mph.
