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?
