A red light flashes every 14 minutes. A blue light flashes every 24 minutes. When will the two lights flash together again, if they last flashed together at 8 AM?

The least common multiple of 14 and 24 is 168.

The lights flash together every 168 minutes.

168 minutes = 2 hours 48 minutes.

If they flashed together at 8 AM, then they'll flash
together again at 10:48 AM.
