A dolphin jumped above the surface of the water. It reached an altitude of 3.5 meters above the surface of the water and then dove 10 meters below the surface of the water. It went from its highest point above the water to its lowest depth in 12.5 seconds. Interpret the quotient to describe the average rate of change in the dolphin’s position. Give your answer to the nearest hundredth.(1 point)

The correct interpretation of the quotient to describe the average rate of change in the dolphin's position is:
The quotient that describes the rate of change in the dolphin’s position is 0.52 meters/second.
The correct interpretation of the quotient to describe the average rate of change in the diver's depth is:
The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.
To find the amount that the car's value decreases per month, we need to divide the decrease in value by the number of months.
The correct answer is:
$333.33
To find the amount that the water in the canteen should change every 10 minutes, we need to divide the amount of water recommended per hour (24 ounces) by 6 (since there are 6 10-minute intervals in an hour).
The correct answer is:
4 ounces
I apologize for any confusion. To find the amount that the water in the canteen should change every 10 minutes, we need to divide the amount of water recommended per hour (24 ounces) by 6 (since there are 6 10-minute intervals in an hour).
The correct answer is:
4 ounces
