Question

A deep-sea exploring ship is pulling up a driver at the rate of 25 feet per minute. The driver is 100 feet below sea level. How many minutes will it take the driver to get to the boat?

Answer 1

4 minutes

Explanation:

To solve this set up an equality

25 feet = 1 minute

To solve, first divide the 100 by the 25 to figure out the factor.

100/25 = 4

We now know that if you multiply 25 by 4 you will get 100. Multiply both sides of the equality to solve the problem

25 feet = 1 minute

25 feet (*4) = 1 minute (*4)

100 feet = 4 minutes
