Luke and Inga are riding the Prince Charming Carousel at Disney World. Luke is on a horse 20 feet from the center. Inga is on a horse 17 feet from the center. Prince Charming has the
carousel spinning at 4 revolutions per minute. (Round to two decimal places if necessary.)

step-by-step explanation:

i think because what else can be a sample of every member

- "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."
