Chapter 5.1, Problem 22P

State the independent variable and the dependent variable in each situation. Then find the rate of change for each situation.

An airplane ascended 3000 feet in 10 minutes and 4500 feet in 15 minutes.

To determine

To find: The rate of change for the given situation “An airplane ascended 3000 feet in 10 minutes and 4500 feet in 15 minutes.”

Answer to Problem 22P

  $300$ .

Explanation of Solution

Given information:

An airplane ascended 3000 feet in 10 minutes and 4500 feet in 15 minutes.

In the given situation, the independent variable is time and the dependent variable is the distance covered.

Rate of change:

  $\frac{\text{Change in the distance}}{\text{Change in time}}=\frac{4500-3000}{15-10}=\frac{1500}{5}=300$

Conclusion:

Therefore, in the given situation, the independent variable is time and the dependent variable is the distance covered. The rate of change is $300$
