Step-by-step explanation: it would be 12:39 because 34 hours is 2 days with a leftover 10 hours. The 89 minutes include an hour so it becomes 11 hours and 29 minutes, add this number to 1:10 and there you go
The next time the stations will play the song at the same time would be at 4:12 P.M. because 18×4=72 and 24×3=72 and this is the first number that they share.
