  1. 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.

  2. 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

  3. no, because they started in synch at 12:00. 70 minutes later it's 1:10.
