The temperature at 6 pm was 0°F. At 10 pm the temperature was 211.2°F. Write an expression that you
can use to find the average change in temperature per
hour during that time. Then evaluate the expression.

Average change in temperature is - 2.8 Fahrenheit per hour.

Step-by-step explanation:

Average change in temperature is the change in temperature divided by the time taken for the change.

Change in temperature = (-11.2) F- 0 F

                                      = -11.2 F

Time taken for the change in temperature = 10 pm

                                                                  = 4 hours

Average change in temperature = Change in temperature / time taken for the change

                                                     = - 2.8 Fahrenheit per hour

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
