A drunkard man walking in a narrowlane takes (5) steps forward and `3` steps backward each stepe of (1) m ling, per second and os on. Determine how long the drunkard takes to fall in a pot `15 m` away from the start.

Text Solution

Verified by Experts

The effective distace travelled by drunkard in ` 8 steps `=5 -3 =2 m`. Therfore, thhe takes `40` steps to move `10` metres. Now he will jave to cover `5` metres more to reach the pit for which he has to take only `5` fprward steps. Therfore, he will heve to take`=40 +5 =45` steps to move `15` meres. Thus he will fall into the pit after takin `45 steps, i.e. after `45` seconds from the start.
