Question

Sita and Gita start walking from the same point on the road but in opposite directions. If Sita walks at the speed of $5km/hr$ and Gita at a speed of $4km/hr$, in how much time will they be $27km$ apart?

Answer 1

Speed of Sita $=5km/hr$

$\Rightarrow$ Time taken by Sita to cover $27km=\frac{Distance}{Speed}=\frac{27}{5}$

$\therefore$ Time taken by Sita to cover $27km=5.4hrs=5hrs25min$

Speed of Gita $=4km/hr$

$\Rightarrow$ Time taken by Gita to cover $27km=\frac{Distance}{Speed}=\frac{27}{4}$

$\therefore$ Time taken by Gita to cover $27km=6.75hrs=6hrs45min$
