Question

A car uses 8 litres of gasoline to travel 160 km. How much gasoline will the car use to travel 400 km?

Answer 1

The car will use 20 liters of gas

Explanation:

160KM/8L = 20KM per liter

400/20 = 20

Answer 2

20 liters of gasoline

Explanation:

Create a proportion where x is the amount of gasoline needed to travel 400 km:

`(8)/(160)` =
`(x)/(400)`

Cross multiply and solve for x:

160x = 3200

x = 20

So, the car will use 20 liters of gasoline to travel 400 km.
