Asubmarine 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.

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
