If at time 3 hours, a car has traveled 145 miles, and at time 7 hours, the car has traveled 357 miles,
what is the car's average rate over the given time interval? Include units in your answer.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It is not clear from the post, to which time interval does the question relate.

Does it relates to the 3-hour interval? - Then the average rate is miles per hour.

Does it relates to the 7-hour interval? - Then the average rate is miles per hour.

If it relates to the entire trip of 3 + 7 hours, then the average rate is miles per hour.

I left it to you to make calculations.

By the way, the words "car's average rate of change" tell a lot about you.
The matter is that such combination of words is not applicable in this context.
The correct term is "car's average rate".

Watch your terminology !!
