Question

If Boojho covers a certain distance in one hour and Paheli covers the same distance in two hours, who travels in a higher speed?

Answer 1

Find the person who travels in higher speed:

Let the distance be $x$

We know that

$\mathrm{Speed}=\frac{\mathrm{Distance}}{\mathrm{Time}}$

Boojho cover the distance in $1\mathrm{hour}$

$\therefore$ Speed of Boojho is:

$$\begin{gathered} \mathrm{Speed}=\frac{x}{1} \\ =x \end{gathered}$$

$\therefore$ Speed of Boojho is $xkm/hr$

Paheli cover the distance in $2\mathrm{hour}$

$\therefore$ Speed of Paheli is:

$$\begin{gathered} \mathrm{Speed}=\frac{x}{2} \\ =\frac{x}{2} \end{gathered}$$

$\therefore$ Speed of Paheli is $\frac{x}{2}km/hr$

So, we can observe that Boojho travels at a speed higher than Paheli.

Hence, Boojho travel at a higher speed.
