Question 761655: There is a circular path around a sport field. Geeta takes 20 minutes to drive one round of the field. While ravi takes 14 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at starting points? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! There is a circular path around a sport field. Geeta takes 20 minutes to drive one round of the field. While ravi takes 14 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at starting points?
---------
20 = 2^2*5
14 = 2*7
-----------
Least common multiple is 2^2*5*7 = 4*35 = 140 minutes
