The function D(t)=8t^2 gives the distance a car going at a certain speed will skid in t seconds.
Find the time it would take for the car to skid 160 feet.
~~~~~~~~~~~~~

Write equation as you read the problem


    8t^2 = 160  feet.


Divide both sides by 8


    t^2 = 160/8

    t^2 = 20

    t   =  = 4.47 seconds    (rounded).    ANSWER

Solved.
