Question

Rizwan lives $7\frac{3}{4}$km away from his workshop.In the morning ,he covers $2\frac{1}{2}$km of this distance on foot and the remaining by a local bus.How much distance is covered by him in the local bus ?

Answer 1

Distance covered by Rizwan by foot

$=2\frac{1}{2}$km

Distance covered by Rizwan by local Bus

$=7\frac{3}{4}-2\frac{1}{2}$

$$\begin{gathered} =\frac{7\times 4+3}{4}-\frac{2\times 2+1}{2} \\ =\frac{31}{4}-\frac{5}{2} \\ =\frac{31-10}{4} \\ =\frac{21}{4} \end{gathered}$$

So distance covered by Rizwan by local Bus$=\frac{21}{4}$km
