Question

If the temperature dropped by 42 degrees over 7 hours, how much did the temperature change per hour?
-7
-6
-35
-49

Answer 1

To find how much the temperature changed per hour, we need to divide the total change in temperature (42 degrees) by the number of hours (7).

42 degrees / 7 hours = 6 degrees per hour.

So, the temperature changed by 6 degrees per hour. Therefore, the correct answer is -6.
