A car starts from rest and accelerates to a speed of 60 mph in 25 seconds. The acceleration during this period is constant. For the next 11 minutes, the car moves with the constant speed of 60 mph. At this time the driver of the car applies the brake, and the car decelerates to a full stop in 15 seconds. The variation of the speed of the car with time is shown in the accompanying diagram. 60 25 s 685 s 700 s Time (s) Determine the total distance (in miles) traveled by the car. (Round your answer to at least one decimal place.) miles Determine the average speed (in mph) of the car over this distance. (Round your answer to at least the nearest integer.) mph Speed (mph)
