    Answer:

    The answer is 1 13/24 hours or 1 hour, 32.5 minutes

    Step-by-step explanation:

    Find a common multiple of the denominators 3 and 8, which would be 24.  Convert the fractions:

    7/8 x 3/3 = 21/24.

    2/3 x 8/8 = 16/24

    Add the two numerators = 37/24 or 1 13/24.  

    1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.

    The answer is 1 13/24 hours or 1 hour, 32.5 minutes
