The average acceleration is .
Acceleration .
when t = 3 sec.
Since Q’s acceleration, for all t in 0 ≤ t ≤ 5, is the slope of its
velocity graph,
Find the distance each auto has traveled. For P, the distance is
For auto Q, the distance is the total area of the triangle and trapezoid
under the velocity graph shown below, namely,
Auto P won the race.
