Answers
Given : a circular jogging track is 800m long. madhavi and mamta . jog daily around this track. madhavi takes 15 minutes and mamta take 20 minutes
To Find : after how much time will they meet at this point
Solution:
a circular jogging track is 800m long.
madhavi takes 15 minutes
mamta take 20 minutes
Find LCM of 15 & 20
60 is the LCM
They will meet after 60 Minutes = 1 hr
1 will complete 4 rounds and another 3 rounds
if they need to meet at any points then
relative speed = 800/15 - 800/20 = 800 /60 m/min
and to meet again one need to cover 800 m extra
800/ (800/60) = 60 Min
Hence in this case also they will meet after 60 minutes
time will they meet after 1 hr
