3. Rupert drove home at an average rate of 58 miles per hour. How many miles did Rupert travel in 5 hours?

290

Step-by-step explanation:

if he drives at 58mph that means he is driving 58 miles in one hour

to find out how many miles he drives in 5 hours, times the number of miles by 5

58x5=290

- "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."
