8.75 minutes

Step-by-step explanation:

This is a simple linear relation between two variables, time and depth

We can solve it by simple inspection like this.

If the diver is 5 feet deep and plans to go 75 feet deep, he must move 70 feet deeper.

At a rate of 8 feet/minute, it will take him/her

70/8 = 8.75 minutes

It is 8 minutes and 45 seconds
