An airplane took four hours to fly 2400 miles in the direction of the jet-stream. The return trip against the jet-stream took five hours. What were the airplane’s speed in still air and the jet-stream's speed?

Solve using a system of equations: J = jet’s speed S = jet-stream speed Distance = rate  time 2400 =  4 2400 =  5 Now solve… Solve using a system of equations: (j + s) (j – s)

Jetstream speed is 60 mph, jet speed is 540 mph. Answer
