Question

a car travels 500km on 25L petrol .how far will the car go on 10 L of petrol? want step by step explanation​

Answer 1

Answer:

Car travels in 500km of 25l

(ratio and proportion method)

25:500::10:x

extremes = means

25*x=500*10

x=500*10/25

x=200

∴ A car can travel 200km in 10l

(Unitary method)

25l of petrol = 500km

1l of petrol = 500/25

10l of petrol = 500/25*10

                    =200

∴ A car can travel 200km in 10l
