Question 59 Exercise 2.3

Q7) A car runs 16km using 1 litre of petrol. How much distance will it cover using $2\frac{3}{4}$ litres of petrol.

Answer:

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
