A car, initially at rest, begins moving at time $t = 0$ with a constant acceleration down a straight track. If the car achieves a speed of 60 miles per hour (88 feet per second) at time $t = 4$ seconds, what is the car's acceleration? Include units in your answer.

acceleration = help (units)

How far down the track will the car have traveled when its speed reaches 60 miles per hour? Include units in your answer.

distance traveled = help (units)
