PLEASE HELP ME WITH THIS ONE QUESTION
What is the perimeter of the triangle?

- "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."

can you put the picture up?

step-by-step explanation:

c

-by-step explanation:

it would be c

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
