2. Alberto runs 3 miles each day. 4. Comple 16 x 3 5 n total miles 3 31 33 32 31 32 31 A. Write an equation using the variablen to model how far he runs in 7 days. 5. Selec to B. How far does he run in 7 days? Jo00

- "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."

combine all like terms then its just a 2 step equation

answer is c chief it always is
