Question

*Given the velocity curve, at which time (t) is the speed of the car the greatest
*What is the net distance traveled by the car over the time interval   0≤t≤8
*What is the total distance traveled by the car over the time interval 0≤t≤8

anonymous · Answer

the velocity was greatest at t=4
the area under the curve but above the x axis minus the area below it is the net distance traveled.
Add those areas to get the total distance, some of which was going back..
