Answer:
Night 12:01:54 Hours.
Step-by-step explanation:
The LCM Of Seconds Is...
2/24,48,72
3/8,16,24
4/2,4,6
2/1,2,3
LCM = 2x3x4x2x1x2x3
= 288.
And,
The Time Of Change Together Is 9:10:24 Hours.
9:10:24 Hours = 9 Hours, 10 Minutes, 24 Seconds.
In Seconds,
9x60x60 + 10x60 + 24 Second.
= 9x3600 + 600 + 24 Second.
= 32400 +624 Second.
= 33024 Second.
Now, The Light Change Together At :
33024/288 Hours.
= 114.6 Hours.
= 00 Hours, 01 Minutes, 54 Seconds.
& The Time Is 00:01:54 Hours.
& The Time 00:01:54 Means Night 12:01:54 Hours.
So, The Lights Change Together At Night 12:01:54 Hours.
