Two traffic lights turn red together at exactly 5: 00 pm. one light is on a 36-second cycle from red back to red while the other is on a 48-second cycle. at what time will they again turn red together? give the exact time, including seconds

5:02:24

Step-by-step explanation:

we need to find the LCM of 36 and 48.

multiples of 36: 36, 72, 108, 144

48: 48, 96, 144

the LCM is 144, so they will both be red in 144 seconds. 144 seconds is 2 minutes 24 seconds, so the time will be 5:02:24

10/60
