The dimensions of a rectangle person are measured in centimeters what unit will the volume of the person be measured in A. Meters
B cubic centimeters
C. Square centimeters
D. Centimeters

it should be b. cubic centimeters

Step-by-step explanation:

the cubic label is used for volume.

please tell me if im incorrect!

- "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."
