If Bob is driving along a toll road and passes the first toll reader at 12:00 and is traveling 50 miles an hour, he then passes the second reader 12 miles later at 12:10.

Using the Mean Value Theorem, can you prove that Bob was driving faster than 55 miles per hour at some point?

Responses

Bob’s average speed was 60 miles/hr and the Mean Value Theorem can be used to prove that he was traveling faster than 55 miles per hour at some point between the two toll readers.

Bob’s average speed was 72 miles/hr and the Mean Value Theorem cannot be used to prove that he was traveling faster than 55 miles per hour at some point between the two toll readers.
