Question

At 3 o’clock the temperature was 65 degrees.At 8 o’clock the temperature was 50 degrees.What is the average rate of change?

Answer 1

The average rate of change in temperature between 3 o’clock and 8 o’clock is 3 degrees Fahrenheit per hour, calculated by subtracting the temperatures at these times and dividing by the number of hours in between.

Step-by-step explanation:

To find the average rate of change in temperature between 3 o’clock and 8 o’clock, we take the difference in temperatures and divide by the difference in time. The temperature at 3 o’clock was 65 degrees, and at 8 o’clock it was 50 degrees. There are 5 hours between 3 o’clock and 8 o’clock.

To calculate the average rate of change, follow these steps:

1. Subtract the later temperature from the earlier temperature: 65 degrees - 50 degrees = 15 degrees.
2. Subtract the later time from the earlier time: 8 o’clock - 3 o’clock = 5 hours.
3. Divide the temperature change by the time change: 15 degrees ÷ 5 hours = 3 degrees per hour.

Therefore, the average rate of change in temperature between 3 o’clock and 8 o’clock is 3 degrees Fahrenheit per hour.
