A drunkard waking in a barrow lane takes ` 5` steps forward and `3` steps backward, followed again `5` steps forward and `3` steps backward, and so on. Each step is ` 1 m`long and requires 1 s`. Determine how long the drunkard takes to fall in a pit ` 13 m` away from start.

Explanation

To solve the problem of the drunkard walking in a barrow lane and falling into a pit 13 meters away, we can break it down into a series of steps:

### Step 1: Determine the net distance covered in one complete cycle
The drunkard takes 5 steps forward and then 3 steps backward. Each step is 1 meter long.

- **Distance covered forward in one cycle**: 5 meters
- **Distance covered backward in one cycle**: 3 meters
- **Net distance covered in one cycle**: 5 m - 3 m = 2 m
