This is a very nice puzzle from a close friend – Maneesh Dube, based out of New Jersey.
Maneesh and his daughter, Nandini, are running around a circular park. Maneesh is running faster than Nandini. How much faster is Maneesh running than Nandini if they keep on meeting only at one point of the circle.
As always, please send your answers to firstname.lastname@example.org and please do share with others if you like the puzzle.
