Question
One light flashes every 2 minutes and another light flashes every 3.5 minutes. Suppose both lights flash together at noon. What is the first time after 1 PM that both lights will flash together ?

every 14 minutes, the lights are in synch. 14*5 = 70 is the lowest multiple of 14 greater than 60.
So, at 1:10 pm they are again together.
So, at 1:10 pm they are again together.

isnt it every 14 minutes meaning at 1:14pm not 1:10pm. Because
2,4,6,8,10,12,14
3.5, 7, 10.5, 14
so they will meet again in every 14 minutes
2,4,6,8,10,12,14
3.5, 7, 10.5, 14
so they will meet again in every 14 minutes
Steve
no, because they started in synch at 12:00. 70 minutes later it's 1:10.

Because the lowest common muliple of 3.5 and 2 is 14. So the largest muliple larger than 60 (1 hour) would be 70. So 12:00 plus 70 mins would be 1:10 PM
