# A drunkard is walking along a straight road. He takes 5 steps forward and 3 steps backward and so on. Each step is 1 m long and takes 1 s. There is a pit on the road 11 m away from the starting point. The drunkard will fall into the pit after?

(a) 21s

(b) 29s

(c) 31s

(d) 37s

The drunkard will fall into the pit after 29s. After taking 5 steps forward and 3 steps backward in 8 seconds, the individual is 2 meters distant from his starting position.

It can be written as:

X = 5-3=2 m in 8 sec

He will be 6 m distant from his starting place after 24 seconds.

He advances another 5 m before falling into a pit 11 m away from his starting point.

Total time T = 24 + 5 = 29 sec.

### Distance and Displacement

Distance and displacement are two quantities that seem to mean the same thing, but have very different definitions and meanings.

• Distance is a scalar quantity that describes "how much ground an object has covered in its travels."
• Displacement is a vector quantity that expresses "how much an object is displaced". This is the global change in the object's position.

Distance is the total distance traveled by the body over a period of time.

Summary:

## A drunkard is walking along a straight road. He takes 5 steps forward and 3 steps backward and so on. Each step is 1 m long and takes 1 s. There is a pit on the road 11 m away from the starting point. The drunkard will fall into the pit after?
