Question

Mrs. Jones got a new freezer. She

plugged it in, and it began to get cold.
The temperature inside the freezer
dropped 12 degrees every hour for
6 hours. What was the change in the
temperature in the freezer over those
6 hours?

Answer 1

The change would be -72°C.

Explanation:

Here, the temperature inside the freezer dropped 12 degrees every hour,

I.e. the change in temperature in one hour = -12°C.

Since, this change is constant for 6 hours,

Thus, the total change in temperature for 6 hours

= 6 × change for 1 hour

= 6 × -12

= -72°C
