Justin runs at a constant rate, traveling 17 \text{ km}17 km17, start text, space, k, m, end text in 222 hours. Write an equation that shows the relationship between ddd, the distance he runs in kilometers, and hhh, the time he spends running in hours.

ddsf

step-by-step explanation:

dfs

- "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."

answer: 5100 just subtract
