Answer:

55

Step-by-step explanation:

Step 1: Divide each mile he drove by the hours:

110 ÷ 2

[tex]\frac{110}{2}[/tex]

= 55

275 ÷ 5

[tex]\frac{275}{5}[/tex]

= 55

Note - the next step is not necessary in this case even though it asked for the average because if both results are the same, then that is the answer.

Step 2: Find the average of the two results:

[tex]\frac{55+55}{2}[/tex]

[tex]\frac{110}{2}[/tex]

= 55

Therefore, the average rate of change is 55 miles per hour.
