A drunkard walking in a narrow lane take...

A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, and again takes 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 into a pit 13 m away from the start.

Text Solution

Verified by Experts

The effective distance travelled by the drunkard in 8 steps `= 5 - 3 = 2 m`.
Now, he has to cover 5 m more to reach the pit for which he has to take only 5 forward steps.
`therefore ` Number of steps = `32 + 5 = 37 `
