Free points to whoever gives me a giveaway afterward. I was going to include myself playing to piano with it, but the video was too big. And bu too big I mean one minute. Its not even letting me post a 1 minute video! Anyway, you can keep these free points if you give me another giveaway afterward.

hi

Step-by-step explanation:

thank you, and I will be doing a giveaway afterward!

Step-by-step explanation:

- "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."
