Question 66578: Two people are running around a track in the same direction. One person does a mile in 4 min. but the second one takes 10 min. If they start at the same time and same place, how long will it take them to be at this same place together if they continue to run. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Two people are running around a track in the same direction. One person does a mile in 4 min. but the second one takes 10 min. If they start at the same time and same place, how long will it take them to be at this same place together if they continue to run.
--------------
The faster one will make 5 loops in 20 minutes.
The slower one will ake 2 loops in 20 minutes.
Then will both be at the starting point 20 minutes
after they start running.
Comment: 20 is the "least common multiple" of 4 and 10.
Cheers,
