Question

Amelia used 6 liters of gasoline to drive 48 kilometers.How many kilometers did Amelia drive per liter?At that rate, how many liters does it take to drive 1 kilometer?

Answer 1

Part 1: 8 km per liter

Part 2: 0.125 liters per km

Explanation:

Part 1:

6x=48

x=48/6

x=8

Part 2:

8km per liter

?liters per km

1/8 = 0.125

0.125 liters per kilometer

Answer 2

Answer: The distance traveled in 1 liter of petrol =8 kilometers

The amount of petrol used to travel 1 kilometer =0.125 liter

Explanation:

Given: The distance traveled in 6 liters of petrol = 48 kilometers

Thus, the distance traveled in 1 liter of petrol =
`(48)/(6)=8\ \text{kilometers}` [ divide 6 on both sides ]

Hence, the distance traveled in 1 liter of petrol = 8 kilometers

⇒ The amount of petrol used to travel 8 kilometers = 1 liter

Then the amount of petrol used to travel 1 kilometer =
`(1)/(8)\ \text{liter}` [divide 48 on both sides]

Hence, the amount of petrol used to travel 1 kilometer = 0.125 liter
