Question

A car requires $5litres$ of petrol to cover $80km$. How many litres of petrol are required to cover $32km$?

Answer 1

Step 1: Finding amount of petrol required for $1km$.

Petrol required for covering a distance of $80km$ $=5litres$

Therefore, petrol required for covering a distance of $1km$ $=\frac{5}{80}litres$

Step 2: Finding amount of petrol required for $32km$

Petrol required for covering a distance of $32km$ $$\begin{gathered} =\frac{5}{80}\times 32litres \\ =2litres \end{gathered}$$

Therefore, $2litres$ of petrol will be required.
