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.
