Validate

Solution:

(c) 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 60 minimum time when they first meet =

∴ They will meet 5 times in 1 h and 2 times in next 2 h.
Therefore, they will meet 7 times between 8 am to 9:30 am
