a vehicle when climbing up a gradient consumes petrol @ 8km per lit while coming down it runs 12 km per lit find its average consumption for to and fro travel between two places situated at the two ends of 25 in a long gradient

Answer 1

Answer:

Given -

Kms driven : 100km

Fuel consumed : 8 litres

To find : how much it will travel in 26 litres of fuel

Solution : First of all find out fuel economy of car how much it traveled in 1litre and multiply your answer with 26litres of fuel

Find per litre fuel consumption

Distance Traveled/fuel consumption = Fuel economy

100/8 = 12.5

The car travels 12.5 km in 1litre of fuel.

2. To find distance covered in 26litre

Sincr car can travel 12.5 in 1 litre of fuel

In 26litre it will cover

Fuel consumption X fuel economy per litre = distance traveled

26 X 12.5 = 325

Therefore car can travel 325 kms in 26litres of fuel.
