true or false

anonymous · Answer

false.

     There is not enough information given to reach the conclusion that the car's speed was restricted to between 50 and 60 mph during the hour.

     The driver could have stopped at a rest stop at 2:10 pm for 40 minutes and then continued the trip at a speed of 60 mph.
