This table shows the range of a soccer kick launched at the same angle at various initial speeds. speed (mph) 25 35 45 55 65
distance (yd) 16 26 31 46 49

Give the best possible estimate of the instantaneous rate of change of the distance when the speed is 50 mph. Also, what units?

I know this is derivative...

y=1/4x-4

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."

40 x 50 = 2000
