5- Sam rode 5 kilometers in his car. His sister Pam rode 4000 meters in her car. Who rode the farthest? (answer in km) *

sam rode further because 5 kilometers is 5000 metres and pam rode 4000 metre therefore sam rode 1kilometres further

Step-by-step explanation:

1km= 1000metres

- "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."
