Validate

Solution:

A covers 2 rounds in

1 {h}

, while

B

covers 3 rounds in

1 {h}

of a circular track.
Since, they are moving the opposite direction, therefore minimum time when they first meet

=\;{60}/{5}=12 {min}

∴

They will meet 5 times in

1 {h}

and 2times in next

2 {h}

.
Therefore, they will meet 7 times between 8 am to

9: 30

am.
