Question

Shikha plants 5 saplings in a row in her garden. The distance between two adjacent saplings is $\frac{3}{4}\mathrm{m}$. Find the distance between the first and the last sapling.

Answer 1

Distance between the first and second saplings = $\frac{3}{4}\mathrm{m}$
Distance between the first and third saplings = $2\times \frac{3}{4}\mathrm{m}=\frac{3}{2}\mathrm{m}$
Distance between the first and fourth saplings = $3\times \frac{3}{4}\mathrm{m}=\frac{9}{4}\mathrm{m}$

Distance between the first and fifth saplings = 4 × $\frac{3}{4}\mathrm{m}=3\mathrm{m}$
