Joshua drove his car a distance of 417.7 miles, and it required 14.2 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers? Hint: Start with 100 km.

100km1×...continueconversion...=num berofLiters

Use the following facts:

417.7 miles = 14.2 gallons for this car
1 km = 0.6214 mi
1 gal = 3.8 L

6L

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."
