    4 weeks

    Step-by-step explanation:

    Equation:

    21 / 1.75 x 3 = Weeks needed

    To calculate

    1.75 hours = 1 hour and 45 mins

    = 105 mins

    1 week he runs 105x3 = 315 minutes

    To make it easier, convert it all to minutes

    21 hours = 1260 minutes

    1260 / 315 = 4
