Answer: 7:42 am
Step-by-step explanation:
Since, A and B move in the same direction along the circle, so they will first meet, each other when there is a difference of one round between the two.
Relative speed of A and B =(6−1)=5 rounds per hour.
Time taken to complete one round at this speed =51hr=12min.
Hence, They shall first cross each other at 7.42am.
