 Question 5.
 Saili plants 4 saplings, in a row, in her garden. The distance between two adjacent saplings is \(\frac{3}{4}\) m. Find the distance between the first and the last sapling.
 Solution:
 
 From the figure, it can be observed that gap between first and last sapling = 3 × Length of gap 1
 Therefore, distance between first and last
 

Question 6.
 Lipika reads a book for \(1 \frac{3}{4}\) hours everyday. She reads the entire book in 6 days. How many hours in all were required by her to read the book?
 Solution:
 Time taken by Lipika to read the book per day = \(1 \frac{3}{4}\) hours = \(\frac{7}{4}\) hours
 Number of days = 6
 Total time taken by her to read the entire book = \(\frac{7}{4}\) × 6 hours = \(\frac{21}{2}\) hours
 = \(=10 \frac{1}{2}\)hours
Question 7.
 A car runs 16 km using 1 litre of petrol. How much distance will it cover using \(2 \frac{3}{4}\) litres of petrol?
 Solution:
 A car can run per litre of petrol = 16 km
 Quantity of petrol = \(2 \frac{3}{4}\) litres = \(\frac{11}{4}\) litres
 So, a car can run for \(\frac{11}{4}\) litres of petrol
