In 1 day, Lipika reads = 1(3/4) hours
Since in 6 days, Lipika will need = 6×1(3/4) = 6x(7/4) = 3x(7/2) = 21/2 hours;

So, the required hours = 10(1/2) hours.

Question 7 :- A car runs, 16-km using 1-litre of petrol. How-much distance will it cover using 2(3/4) litres of petrol?

In 1 litre of petrol, the car covers distance = 16 km.
In 2(3/4) litres of petrol, the car will cover distance = 2(3/4) × 16 = (11/4)x16;

So, the required distance = 44 km.
