A drunkard walking in a narrow lane takes $$5$$ steps forward and $$3$$ steps backward, followed again by $$5$$ steps forward and $$3$$ steps backward, and so on. Each step is $$1$$ m long and requires $$1$$ s. There is a pit on the road $$13$$ m away from the starting point. The drunkard will fall into the pit after:

Suppose you are riding a bike with a speed of $$20$$ m/s due east relative to a person $$A$$ who is walking on the ground towards the east. If your friend $$B$$ walking on the ground due west measures your speed as $$30$$ m/s due east, find the relative velocity between two reference frames $$A$$ and $$B$$:

 1 The velocity of $$A$$ with respect to $$B$$ is $$5$$ m/s towards the east. 2 The velocity of $$A$$ with respect to $$B$$ is $$5$$ m/s towards the west. 3 The velocity of $$A$$ with respect to $$B$$ is $$10$$ m/s towards the east. 4 The velocity of $$A$$ with respect to $$B$$ is $$10$$ m/s towards the west.
