Question

A vehicle covers a distance of 43.2 km in 2.4 liters of petrol. How much distance will it cover in one liter of petrol?

Answer 1

Step-by-step explanation:

Distance travelled in 1 liter of petrol = 43.2/2.4 = 18 km.

Answer 2

Answer:

This is a proportion.

Km to liters.

43.2km is to 2.4 l as x km is to 1 l

as an equation this is:

43.2/2.4 = x/1

x= 43.2/2.4= 18 km per liter

We now know how much distance we get for every liter of petrol so for 12 liters we could set up another proportion as in

43.2/2.4 = x/12

or we could simply take the 18 km/l and multiply it by 12 liters... 18(12) = 216 km

note: we get the same answer if we work the proportion...

43.2/2.4 = x/12

2.4x = 43.2(12)

x = 43.2(12)/2.4 = 216 km
