1.	The traffic lights at three different road crossing change after every 108 seconds,135 seconds, 162 seconds respectively. lf they change simultaneously at 7 a.m. atwhat time will they change simultaneously again?
Answer» Answer: Step-by-step explanation: We know that in order to find the time when the three lights will change simultaneously again after 7 a.m., we need to find the LCM of 48, 72, and 108. Hence, converting 432 seconds into minutes and seconds, we get: 432 seconds = 7 minutes and 12 seconds.
