Question

A bus travels at $\mathrm{v}\mathrm{km}\mathrm{per}\mathrm{hour}$. It is going from Daspur to Beespur. After the bus has traveled $5\mathrm{hours}$, Beespur is still $20\mathrm{km}$away. What is the distance from Daspur to Beespur ? Express it using $\mathrm{v}$

Answer 1

Formation of an expression

Given that, Speed of bus $=\mathrm{v}\mathrm{km}/\mathrm{hr}$

We know that ,$\mathrm{Distance}=\mathrm{speed}\times \mathrm{time}$

Distance traveled by the bus in$5\mathrm{hours}=\mathrm{v}\times 5\mathrm{km}=5\mathrm{v}\mathrm{km}$

According to the question,

Distance from Despur to Beespur$=$ Distance traveled by in $5\mathrm{hours}+20\mathrm{km}$$=(5\mathrm{v}+20)\mathrm{km}$

Hence, the distance from Despur to Beespur is $(5\mathrm{v}+20)\mathrm{km}$
