    answer:

    7:00 amthe time they will announce the next weather forecast all at the same time is 7:00 am

    Step-by-step explanation:

    supposed all radio stations starts at announcing at 11:00 am

    given:

    radio #1: announced every 2 hrs

    radio #2: announced every 4 hrs

    radio #3: announced every 5 hrs

    since the we are looking for the time they will announce the next weather forecast all at the same time...

    step 1: LCM of the hours given

    the LCM of 2, 4 and 5 should be 20

    (this refers where all the station with their respective given hours where they are scheduled to announce)

    step 2: set 20 as the number of hours will be added to starting hour where all stations starts announcing at (11:00 am

    11:00 am + 20 hrs. = 7:00 am

    or

    (for better understanding)

    11:00 am + 12 hrs = 11:00 pm

    11:00 pm + 8 hrs = 7:00 am

    this solution was based on my understanding, correct me if I'm wrong or if i have misinterpreted the problem
