Q7) A car runs 16km using 1 litre of petrol. How much distance will it cover using 2\frac{3}{4} litres of petrol.
Solution 7
In 1 litre of petrol, the car covers 16km distance.
In 2\frac{3}{4} l of petrol, the car will cover 2\frac{3}{4} x 16 km distance
= 2\frac{3}{4} x 16 km = \frac{11}{4}\times16\ =\ 11\times4km\ =\ 44km
Hence, the required distance = 44km
