Hayden is a manager at a landscaping company. he has 3 workers to
landscape an entire park, cody, kaitlyn, and joseph. cody can complete
the project in 8 hours. kaitlyn can complete the project in 6 hours.
joseph is new, so no one knows how long it will take him.
hayden
assigns all of them to complete the park together. explain to hayden
how this project can tell him how long it would take joseph to complete
the project if he worked by himself. use complete sentences.

tell him to get a real job lol

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."
