Expert Solution
Step 1

Physics homework question answer, step 1, image 1

Slope of car one:

slope=velocity=v=xfinal-xinitialtfinal-tinitial      we can take the boundary points to find the slope because the line is straight or the slope is same everywhere:thenv=100-020-0= 5 m/s

From the graph its clear that both the cars are at same position when

t=20s

and both cars have travelled a distance from graph in 20s

x=100 m
