Can someone with this

if you know the number of yards for a measurement, you can change that measure to meters by multiplying the number of yards by 0.9144.

a. write a function rule that relates meters to yards.

b. how many meters are equivalent to 7,200 yards? round your answer to the nearest hundredth, if necessary.

c. how many yards are equivalent to 2,500 meters? round your answer to the nearest hundredth, if necessary.

b. is 6583.68 meters

c. is 2,734 yards

- "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."
