Verified Answer
They shall walk 7 rounds from 8:30 to 9:30 each other walk in this A w...
Ans.

Method to Solve :

Let us treat circular motion in degrees. 1 round = 360�

Speed of A

= 2 round/hr. = 720� in 60 min = 360� in 30 min

= (360�/30) in 1 min.

= 12� / min.

Speed of B

= 3 round/hr. = 1080� in 60 min = 540� in 30 min

= (540�/30) in 1 min.

= 18� / min.

Since A and B are moving in the opposite directions, they complete 360� together, while crossing each other.

Let it take n minutes to make a round (360�) together.

n (12�+18�) = 360�

n=360�/30�

n=12

They cross each other once in 12 minutes.

Between 8:00 am to 9:30 am, there are 90 minutes.

The number of crosses = 90/12 = 7.5
