Question 19 of 20intermediate🔧 ApplyShort Answer3 marks

Find out how many kilometres a vehicle travels per litre of petrol or diesel. Ask about different vehicles. How will you compare them?

Correct Answer

Different vehicles travel different distances per litre of fuel.

For example, a scooter may travel approximately 50-60 kilometres per litre, a car may travel 15-20 kilometres per litre, and a truck may travel 4-6 kilometres per litre.

To compare them, one can create a table listing each vehicle type and its kilometres per litre, then rank them from most efficient (highest km/l) to least efficient (lowest km/l).

Vehicles that travel more kilometres per litre are more fuel-efficient.

Explanation

The chapter mentions that fuels such as petrol and diesel are sources of energy for vehicles. This activity encourages students to research and compare fuel efficiency across different vehicles, helping them understand how energy sources are used differently by various vehicles.

Solution Steps

  1. Different vehicles have different fuel efficiency rates measured in kilometres per litre

  2. Scooters travel approximately 50-60 km per litre

  3. Cars travel approximately 15-20 km per litre

  4. Trucks travel approximately 4-6 km per litre

  5. Create a comparison table listing vehicle types and their km/l values

  6. Rank vehicles from most efficient (highest km/l) to least efficient (lowest km/l)

  7. Higher kilometres per litre indicates better fuel efficiency
