Question

A car travels 432 km on 48 litres of petrol. How far would he travel on 20 litres of petrol? Direct and inverse proportion

Answer 1

Answer:

distance travelled in 48litre=432

distance travelled in 1litre=432/48

distance travelled in 20 litres=432/48×20

=180

Answer 2

With 48 liters of petrol the car can travel 432 km

with 1 liter of petrol, the car can travel (432/48)km

with 20 liters of petrol the car can travel (432*20/48) km

                                                               = (9*20) km

                                                              = 180 km

So, with 20 liters of petrol, the car can travel 180 km.
