Question

A car uses 50 litres of fuel to complete a 400kmalong a high way. How far will it work if it uses 20 litres

Answer 1

`\huge\boxed{\sf 160 \ km}`

Explanation:

Given that,

50 liters = 400 km

Using unitary method.

• Divide both sides by 50

50/50 liter = 400/50 km

1 liter = 8 km

• Multiply both sides by 20

1 × 20 liter = 8 × 20 km

20 liters = 160 km

`\rule[225]{225}{2}`
