ProblemFor the information given below estimate the velocity of the car over the 10 second interval using 5 subintervals and midpoints.
Car velocity and time:
time (t) velocity
0 0
1 20
2 35
3 48
4 62
5 75
6 85
7 93
8 99

i just don't know which times i should take the midpoints. I am debating between taking times at (1,3,5,7,9) and (2,3,6,8,10). can sumone help me?

I would take the midpoints at (1,3,5,7,9). Just because 10 isn't a midpoint. You don't know the value at 11.

It shouldn't really matter ... but midpoints are always the best.

For understanding plot these points and see what happens
if pick left points, middle points, or right points
