Find the volumes of prism a and prism b and then find the ratio of the volumes.

prism a: a rectangular prism a length of 6 m, width of 2 m, and height of 3 m.

prism b: a rectangular prism a length of 12 m, width of 4 m, and height of 6 m.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
