The sides, top, and bottom of a storage bin are made of wood. the storage bin measures 2 meters wide, 3 meters long, and 2 meters tall. which unit of measurement is the correct one to use to figure out the amount of wood needed to build the storage bin? a. straight m b. text m end text squared c. text m end text cubed

- "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."
