## Homework Statement

*A point moves rectilinearly in one direction. The figure shows the distance*

**s**

*traveled by the point as a function of time. Using the graph, find:*

*The average speed of the point during the movement time.**Maximum speed**The moment t*_{0}in which the instantaneous speed is equal to the average speed averaged over the first t_{0}seconds.

## Homework Equations

v=Δs/Δt

a=(v-v

_{0})/Δt

## The Attempt at a Solution

I tried the first part using the formula v=Δs/Δt, by looking at the picture I did it like this: v=(2.0m-0m)/20s-0s = 0.1m/s. Is it correct?

My problem is with the second and third part. How do I calculate the maximum velocity and how do I find the moment where the instantaneous velocity is equal to the average speed averaged over the first t

_{0}seconds? Thanks.
