Students measure the velocity of a car as it races along a track in a clockwise direction. Their measurements are detailed below:

Question

Time (sec) | Velocity (in/sec)
0 | 4
1 | 8
2 | 10
3 | 6
4 | 9
5 | 12
6 | 5
7 | 8
8 | 10
9 | 6
10 | 12

Estimate the distance traveled by the car over the 10-second interval.

Answer 1

Take the average speed during each second times one second and add

6+9+8+7.5+10.5+8.5+6.5+9+8+9

= 82
