    Greg exercises for 310 minutes more than the amount of time Marta exercises

    Step-by-step explanation:

    The expressions for the total number of minutes each exercise in a month is as follows;

    Total number of minutes in a month=Number of minutes per day*number of days in a month

    For Marta;

    Number of minutes per day=30

    Number of days in a month=31 days

    replacing;

    Total number of minutes in a month = (30*31) = 930 minutes

    For Greg;

    Number of minutes per day=40

    Number of days in a month=31

    Total number of minutes in a month = (40*31) = 1,240 minutes

    To get how many more minutes Greg exercises in a month than Marta;

    (Total number of minutes in a month Greg exercises-Total number of minutes Marta exercises)

    where;

    Total number of minutes in a month Greg exercises=1,240 minutes

    Total number of minutes Marta exercises=930 minutes

    replacing;

    (1,240-930) = 310 minutes

    Greg exercises for 310 minutes more than the amount of time Marta exercises
