The problem can be solved by setting up an equation based on the information given.

Let's denote the initial speed as 's' and the initial time as 't'.

According to the problem, when the man goes at 4/5th of his speed, he takes 25 minutes more than his usual time.

This can be expressed as:

t + 25 = t/(4/5)

Solving this equation will give us the initial time 't'.

First, simplify the right side of the equation:

t + 25 = 5t/4

Then, multiply all terms by 4 to get rid of the fraction:

4t + 100 = 5t

Subtract 4t from both sides:

100 = t

So, the initial time taken by the man to travel was 100 minutes.

Therefore, the correct answer is 100 min.
