Q:

Let the speed of Kaushik be **Sk** and speed of Piyush be **Sp** and let the time taken by Piyush be** t** second then,

$\frac{\mathbf{Sk}}{\mathbf{Sp}}\mathbf{}\mathbf{=}\mathbf{}\frac{{\displaystyle \frac{\mathbf{800}}{\mathbf{t}\mathbf{+}\mathbf{20}}}}{{\displaystyle \frac{\mathbf{600}}{\mathbf{t}}}}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{2}}{\mathbf{3}}\left(\mathrm{since}\mathrm{given}\mathrm{ratio}\right)$

t = 20 s

Speed of Piyush = Sp = 600/20 = 30 m/s

and Speed of Kaushik = 800/40 = 20 m/s
