The temperature dropped 3°c every hour for 5 hours. write an integer that represents the change in temperature

The required integer is -15.

Step-by-step explanation:

Given,

The temperature dropped 3°c every hour,

So, the change in temperature every hour = -3°C

Total number of hours for which the temperature were changed = 5,

Thus, the total change in temperature = change for an hour × total number of hours,

= -3° × 5

= -15°

Hence, the integer that represents the change in temperature is -15.
