36 miles

Step-by-step explanation:

If she can drive 12 miles only using 1/3 of a gallon of gas, that means if she uses a full gallon  (3/3) she would be driving 36 miles.

12/1  x  1/3

36/1  x  3/3

Multiply the numerators by 3.

- "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."
