Solution

The correct option is D Speed of Ram is more than that of Shyam.
Given: Distance = 100 $m e t r e s$ .
Time taken by Ram = 20 $s e c o n d s$
Time taken by Shyam = 25 $s e c o n d s$
Since we know that $s p e e d = \frac{d i s t a n c e}{t i m e}$
Speed of Ram = $\frac{100 m}{20 s} = 5 m / s$
Speed of Shyam = $\frac{100 m}{25 s} = 4 m / s$
So, we can say that speed of Ram is more than that of Shyam.
