Question

A plane flies 405 km on 90 litre of fuel. 1 question how much is needed for 540 km? 2 question how far can it go in 50 litres

Answer 1

Distance flied on 90 liters of fuel= 405 km

Distance flied on 1 litre of fuel= 405/90

                                                 =4.5

1. Fuel needed to fly 540 km= 4.5*x=540

                                                  540/4.5 =120

                        →we will need 120 litres of fuel to fly 540 km

2. Distance on 1 litre of fuel= 4.5 km

   Distance on 50 litres of fuel= 4.5*50

                                                  =225 km

                          →we will be able to fly 225 km on 50 litres of fuel.
