Question

29.A scuba diver's vertical position in relation to the surface of the water changes by -90 ft in 3 minutes.What is the average change in the diver's vertical position for each minute?

Answer 1

-30 feet every minute.

Step-by-step explanation

The scuba diver's position in relation to the surface of the water changes by -90 ft in 3 minutes.

We want to find his average change in position every minute.

To do thus, we have that every 3 minutes, the position changes by -90 feet:

3 minutes = -90 feet

1 minute = x

Cross multiply:

x * 3 = 1 * -90

=> x = -90 / 3

x = -30 feet

So, every minute, the scuba diver's position changes by -30 feet
