Given : A jogging track is 500 meters long , jogger takes 10 minutes to complete one lap , other jogger takes 8 minutes
To Find : after how many hours , will they meet at starting point
Solution:
A jogging track is 500 meters long
jogger takes 10 minutes to complete one lap
other jogger takes 8 minutes
To find time they meet again at starting point
we need to find LCM of both times
10 & 8
10 = 2 * 5
8 = 2 * 2 * 2
LCM = 2 * 2 * 2 * 5
= 40 Minutes
60 minutes = 1 hr
40 minutes = 40/60 = 2/3 hrs
after 2/3 hrs they will meet at starting point
