1. The problem statement, all variables and given/known data 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 2. Relevant equations 3. 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!
