Question

A cave diver descends 110 feet in 10 minutes at a constant rate. Express the rate of the cave​ diver's change in position as a rational number in the form of a quotient of integers.

Which of the following expressions shows the rate of the cave​ diver's change in​ position?

Answer 1

Rate of change

• Change in distance/Change in time
• -110/10
• -11ft/min

Answer 2

• -110/10 ft/min

Explanation:

Since the position changes to negative, the rate is:

• -110 ft / 10 min =
• -110/10 ft/min =
• -11 ft/min
