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

-7
-6
-35
-49

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.

To find the temperature change per hour, we can divide the total temperature drop of 42 degrees by the total number of hours, which is 7.

Temperature change per hour = Total temperature drop / Total number of hours

Temperature change per hour = 42 degrees / 7 hours

Temperature change per hour = 6 degrees

Therefore, the temperature changed by 6 degrees per hour.

So, the correct answer is -6.

To find the temperature change per hour, you can divide the total temperature change by the number of hours.

In this case, the temperature dropped by 42 degrees over 7 hours. To find the temperature change per hour, you can divide 42 by 7:

42 degrees / 7 hours = 6 degrees per hour

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