At 1200 hrs.
if a nd b are their speeds, then
69a+54b= 60a+60b
9a=6b
a/b= 2/3 or a= 2b/3 or b= 3a/2
length of track = 60a+60b = 60a+90a=150 a units
A will take 150 minutes to cover one round whereas B will take 100 mins to cover one round.

They both will meet at starting point after 300 mins completing 2 rounds and 3 rounds respectively.
so they will meet again at starting point after 300 mins or 5 hrs i.e. at 1200 hrs
