## Homework Statement

The graph is of a runner-

time(min) is the x

position(x1000 m) is the y

these are the points

0,0

10,3

20,3.5

30,4.5

The question is- For the time interval between 10 min and 20

min, what is the runner’s displacement?

Answer in units of m

## Homework Equations

## The Attempt at a Solution

The position for 10 min is 3000 and the position for 20 is 3500. I subtracted 3500 from 3000 to get 500, what i thought would be the displacement. This is not the answer however and i don't know any other way to work out this problem. Help is appreciated, thanks!
