Hari covers $100 \text{ m}$ distance in $36$ seconds. Ram covers the same distance in $45$ seconds.
In a $100 \text{ m}$ race, Hari ahead from Ram is:

Solution

Speed of Hari
$=\frac{100}{36}=\frac{25}{9} \text{ m/s}$

Speed of Ram
$=\frac{100}{45}=\frac{20}{9} \text{ m/s}$

In 36 seconds (when Hari finishes race):

Distance covered by Ram

$=\frac{20}{9}\times 36$

$=80 \text{ m}$

So Hari wins by

$100-80=20 \text{ m}$
