Question

A car travels $59.5$ km in $3.5$ litres of petrol. How many kilometres will Ramneek drive in $21$ litres of petrol?

Answer 1

In $3.5$ litres, the car travels $59.5$km
In $1$ litre, the car travels $\frac{59.5}{3.5}$km
In $21$ litres, the car would travel $\frac{59.5\times 21}{3.5}$km
$=\frac{595\times 21}{35}$km
$=357$km
$\therefore$ Ramneek will drive $357$ km.
