Solve the system of equations

You TryAn airplane flew for 5 hours with a tail wind of 25km/h. The return flight against the wind took 6 hrsFind the speed of the airplane HINT: speed is rate

Opposite Directions Two trains leave town at the same time going opposite directionsSlow train is going 60 km/hFast train is going 120 km/hIn how many hours will they be 300 km apart?

Solve the systemDistance of Slow Trian plus Distance of Fast Train is 300 60t + 120t = 300
