The graph shows the numbers of miles two cars travel. Car B travels more miles than Car A each hour.

explanation:

the graph is shown in distance(m) against time(h).

to get the slopes of the cars, you use this formula

(change in distance)/(change in time)

which is basically

slope = (y₂ - y₁)/(x₂ - x₁)

car B:

point at rest is (0,0) and another point is (1,40)

slope = (40-0)/(1-0)

         = 40/1

         = 40

so car B is going 40 miles an hour.

car A:

point at rest is (0,0) and another point is (1,24)

slope = (24 - 0)/(1 - 0)

         = 24/1

         = 24

so car A is going 24 miles an hour.

to find how much faster car B is going than car A

24
