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