Question

Find the rate of change from two hours of use and 30 minutes of use.

A) 4 units per hour
B) 2 units per hour
C) 8 units per hour
D) 1 unit per hour

Answer 1

The rate of change from 30 minutes of use to 2 hours of use is approximately 26.67 units per hour.

Step-by-step explanation:

The rate of change can be found by subtracting the initial value from the final value and dividing by the change in time. In this case, the initial value is the amount after 30 minutes of use and the final value is the amount after 2 hours of use. Let's say the initial amount is 30 units and the final amount is 70 units.

The rate of change is calculated as (70 - 30) / (2 - 0.5) = 40 / 1.5 = 26.67 units per hour.

Therefore, the rate of change from 30 minutes of use to 2 hours of use is approximately 26.67 units per hour.
