The petrol consumption rate of a new model car 'Palto' depends on its speed and may be described by the graph below.
Manasa makes a 200 km trip from Mumbai to Pune at a steady speed of 60 km per hour. What is the amount of petrol consumed for the journey?
Fuel consumption is given in litre per hour. It is, therefore, clear from the graph that in travelling 60 km fuel consumption is 4 litres. Hence in travelling 200 km fuel consumption will be = 13.33 litres
