The velocity of a car (in miles per hour) is given by
v(t) = 61.25t − 17.5 t^2
where t is in hours. Write a definite integral for the distance the car travels during the first 2.5 hours. Use your graphing calculator to find this distance.

    d = 61.25 t^2/2 - 17.5 t^3/3 + 0

    if t = 2.5
    d = 191.4 - 91.1 = about 100 miles
