Suppose the temperature outside drops 4 degrees each hour. How much will the temperature change in 5 hours?

-4*5 = -20

To calculate how much the temperature will change in 5 hours, you need to multiply the rate of temperature drop by the number of hours.

In this case, the rate of temperature drop is 4 degrees per hour. So to find the total change in temperature in 5 hours, you would multiply 4 degrees by 5 hours.

4 degrees/hour * 5 hours = 20 degrees

Therefore, the temperature will change by 20 degrees in 5 hours.
