    First you change everything into the same unit.
    60 mins = 1 hr
    12*60= 720 mins
    720 + 30 = 750 mins total
    750 / 5 = 150 mins
    If you need to change that back into hours and minutes...
    150 / 60 = 2.5 hrs
    = 2 hrs 30 mins

    Or you could simply do this:
    12 hrs 30 mins = 12.5 hrs
    12.5 / 5 = 2.5
    2.5 hrs = 2 hrs 30 mins

    Follow the same strategy on the other problems. If you need any more help or another example, just ask.
