Quizplus · Accepted Answer

The distance traveled by the car is the area under the velocity-time graph. Using 8 subintervals of length 1 with left-end point values, the area can be estimated as:(10)(1) + (24-10)(1) + (20-24)(1) + (30-20)(1) + (33-30)(1) + (35-33)(1) + (12-35)(1) + (5-12)(1) = 164 in.
