Answer :
The time when the lights will flash together again is at 10.32 pm.
What time will the lights flash together again?
To find out when all three lights will flash together again, we need to find the least common multiple of the flash intervals for each light (6 seconds, 8 seconds, and 10 seconds).
The LCM of 6, 8, and 10 is determined as;
6 = 2 x 3
8 = 2³
10 = 2 x 5
LCM = 2³ x 3 x 5 = 120
So, all three lights will flash together again every 120 seconds.
120 s = 2 minutes
Therefore, the lights will flash together again every 2 minutes.
Starting from 10:30 p.m., if we add 2 minutes, the lights will flash together at 10:32 p.m.
