Answer 1

Answer:

The pilgrim traveled 20 kms on foot.  

Step-by-step explanation:

Let the distance traveled by the pilgrim on foot be 'x' kms.

Then the distance traveled on bullock cart be (50 - x) kms.

A.T.Q

$\frac{x}{4} + \frac{50 - x}{12} = 7.5\\ \\\frac{3x + 50 - x}{12} = 7.5 \\2x + 50 = 7.5 * 12\\2x = 90 - 50\\2x = 40\\x = 20.$
