Paul made a list of chores he needed to complete before his father came home from work and he showed the time it would take him to complete each chore. If Paul's father is expected home at 6:30 p. m., what is the latest time Paul could begin his chores?

A. 3:20 p. m.
B. 3:30 p. m.
C. 3:40 p. m.
D. 3:50 p. m.

the answer is c just got it on ed

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."
