Aria walked down a trail into a valley. V(d)V(d)V, left parenthesis, d, right parenthesis models Aria's vertical distance from the top of the valley (in kilometers) after walking ddd kilometers along the trail. What does the statement V(3)<3V(3)<3V, left parenthesis, 3, right parenthesis, is less than, 3 mean?

a² + b²= c²

24² + 7² = c²

c= 25

- "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."
