**Question 5 :- Saili plants, 4-saplings, in a row, in her garden. The distance between two adjacent saplings is 3/4 m. Find the distance, between the first and the last sapling.**

**Solution 5:- **

Number of saplings in a row = 4

Distance between two adjacent saplings = 3/4 m

Distance between the first and the last sapling = 3 x (3/4) = 9/4 = 2(1/4) m.

**Question 6 :- Lipika, reads a book for 1(3/4)-hours everyday. She reads the entire-book, in 6 days. How many hours in all were required by her, to read the book?**

**Solution 6 :-**

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?**

**Solution 7:-**

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.
