Answer 1

A water wave travels 36 meters in 15 seconds. What is the speed of the wave?

2.4 m/s

Answer 2

Since the question above is looking for the SPEEd of the WAVE, the formula that should be used is SPEED = DISTANCE / TIME. You just need to substitute the distance (36 meters) and the time (15 seconds) to the formula. You should be able to get SPEED = 2.4 m/s.
