B

Step-by-step explanation:

to find the median of a set of numbers, start off by arranging them in numerical order. from there, cut off pairs on each end until you have only one center number left. if you have an even amount of numbers, then average the two middle ones you're left with after you did the pair cutting

i would need to see the dot plot : )

- "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."
