In constructing a graph that compares average water usage per household in different communities, you choose to use cubes of different sizes. if the cubes are drawn so that their volumes are proportional to the volumes of water usage in different communities, is the resulting graph misleading? why or why not?

answer choices are
no, using volume in graphs is never misleading.

no, the volumes of the cubes are proportional.

yes, the volumes of the cubes should be proportional.

yes, using volume in graphs is always misleading.

- "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."
