Carole was scuba diving and descending at a rate of 4.5 feet per second. If she stopped to look at coral that is 36.9 feet below the surface, how long did it take her to reach that depth?

Answer :

Speed = distance / time

time = distance / speed

Distance = 36.9 ft

Speed = 4.5 feet per second

Replacing:

Time = 36.9 / 4.5 = 8.2 seconds
