The car would travel a distance of 400 km using 20 litres of petrol
How to determine the distance travelled?
The given parameters can be represented using the following scale ratio :
Scale = 340 km : 17 litres
For 20 litres of petrol, we have:
Distance : 20 = 340 km : 17
Express as fraction
Distance/20 = 340 km/17
Multiply both sides by 20
Distance = 400 km
Hence, the car would travel a distance of 400 km using 20 litres of petrol
