    Answer:

    Step-by-step explanation:

    we have to find LCM because the action repeats again so its a multiple.

    30=3*2*5

    36=3*3*2*2

    45=3*3*5

    therefore LCM is 3^2 *2^2*5=180

    therefore they will ring after 180 mins

    that is after 3 hrs

    so they will ring again at 11 a.m

    hope the ans helps..

    pls mark as the brainliest..
