Answer 4

Well, so. 20 minutes taken by Geeta and 14 by Ravi for one round of the park.

So, when they meet again at the starting point, the time would be some common multiple of 14 and 20, and the least time after which this happens will be the LCM of 14 and 20.

Answer 5

Yeah 140 minutes is correct-o!
