Question

A plane flies 405 km on 90 litres of fuel how much fuel is needed for 540 km?how far can not go in 50 litres?

Answer 1

Step-by-step explanation:

405:90::540:x

x=90×540/405

x=120litres

405:90::y:50 (y is maximum distance it can travel)

y=225km

Answer 2

405km = 90 L

=> 1 km = 90/405 L

=> 540 km = 90/405 x 540 L

= 120 L

Hence the amount of fuel needed for 540km is 120 litre

450 km = 90 L

=> 450/90 km = 1 L

=> 450/90 x 50 km = 50 L

=> 50 L = 250 km

Hence the plane can travel 250 km with 50L
