Question

car that I own can go 150 km with 25 litres of petrol how far it can go with 30 litres of petrol

Answer 1

Distance covered with 25 litres of petrol = 150 Km

Distance covered with 30 Litres of petrol= 150/25 × 30 = 180 Km (Using Unitary Method)

Answer 2

Given:

Distance = D1 = 150km

Quantity of petrol = P1 = 25l

To Find:

Distance travelled if there is 30l of petrol

Solution:

Let the distance covered by 30l of petrol be = x

Using the formula -

Distance1/ Petrol1 = Distance2/Petrol2

Substituting the values -

= 150/25 = x/30

x = 150 × 30/25

x = 6 × 30

x = 180

Answer: Distance travelled if there is 30l of petrol is 180km
