Answer:
03:24 PM
Step-by-step explanation:
Given

WMTH = Every 12 minutes
WMSU = Every 8 minutes
Required
Determine when they both play the song
To do this, we simply solve for the LCM of 8 and 12
List the factors of 8 and 12


From the above, the least common multiple is 24
This means that the song will be played on both stations 24 minutes after 3:00PM
<em>In other words, 03:24 PM</em>
