What is known?
A two wheeler covers a distance of \(55.3\rm{ km}\) in \(1\) liter of petrol.
What is unknown?
How much it will cover in \(10\) liters of petrol.
Reasoning:
By using Unitary Method we can simply multiply \(55.3\) by \(10\) to get answer.
Steps:
Distance covered by two wheeler in \(1\) liter of petrol \(=\rm{}55.3\, km \)
Distance covered by \(10\) liter of petrol \(=\rm{} 55.3 × 10 =\rm{}553.0\, km \)
Therefore, it will cover a distance of \(\rm{}553 \,km\) in \(10\) liter of petrol.
