Question

A submarine dives 300 feet every 2 minutes,and 6750 feet every 45 minutes.Find the constant rate at which he submarine dives.Give your answer in feet per minute and in feet per hour.

Answer 1

The answer is 150 feet/minutes and 9000 feet/hour

In order to find the constant rate per minute, we just need to divide the diving distance with the time needed to do so.

300/ 2 minutes = 150 feet/ minutes
6750/45 minutes = 150 feet/minutes . . . .proof there is no acceleration


So, the constant rate per hour will be
150x60 = 9000 feet/hour
