53 Suman and Sujata travel the same distance at speeds of 10 km/hr and 12 km/hr respectively.

Solution:

Let the distance traveled by each be d km.

Time taken by Suman $= \frac{d}{10}$ hours

Time taken by Sujata $= \frac{d}{12}$ hours

Given, the difference in time is 36 minutes $= \frac{36}{60} = \frac{3}{5}$ hour.

So,

$\frac{d}{10} - \frac{d}{12} = \frac{3}{5}$

$\frac{6d - 5d}{60} = \frac{3}{5}$

$\frac{d}{60} = \frac{3}{5}$

$d = \frac{3}{5} \times 60 = 36$

Therefore, the distance traveled by each is 36 km.

Answer:  36 km / 36 किमी
