Answer:
After programs start at 6 a.m, an ad is repeated every 4 minutes on one radio station and every 6 minutes on another. The ad broadcast together from both stations at 6:12 a.m
Step-by-step explanation:
To get the time the ad broadcast from both stations, we need to get the duration taken for this to happen.
To get this, let's get the LCM of 6 and 4.
The LCM of 6 and 4 is given by:
4 = 2 × 2
6 = 2 × 3
The LCM = 2 × 2 × 3 = 12 minutes
The ad broadcast together from both stations after 12 minutes.
So, the time is given by:
6.00 + 12 = 6:12 a.m
