Question

A bike consumes 28 liters of petrol in covering a distance of 1,260 km.How much petrol will be needed to cover a distance of 3,600 km ?

Answer 1

1,260 km : 28 litres of petrol

So, 1 km = 28/ 1260 = 4/180 = 1 / 45 litres of petrol

So, 3600 = 1/ 45 * 3600 = 3600/ 45 = 400/5 = 80/1 = 80 litres of petrol

Answer = 80 litres of petrol will be needed to cover a distance of 3,600 km
