Question

In a firing range, 4 shooters are firing at their respective targets. The first, the second, the third and the
fourth shooter hit the target once in every 5s, 6s, 7s and 8s respectively (s = seconds). If all of them hit
their target at 9:00a.m., when will they hit their target together again?​

Answer 1

Answer:

9:14 AM

Step-by-step explanation:

Find LCM to calculate the next time they will hit their target simutaneously

LCM of 5, 6, 7 and 8 = 840

Time in mins = 840/60 = 14 mins

Next time they'll hit together = 9 :00 + 00:14

= 9:14 AM
