    Answer: 8 days, 3 hours, 12459 minutes

    Step-by-step explanation:

    60 beats = 1 mins

    747,533 beats = ?

    Represent the unknown minutes with z

    60 x z = 747,533 x 1

    60z = 747,533

    z = 747,533/60

    z = 12458.9 ≅ 12459 mins ... in minutes

    But it takes 24 x 60 mins = 1 day i. e. 1440mins

    hence,

    12459 / 1440 = 8.6520 ... 8 days

    12459 / 3600 = 3.5 hours ... in hours

    Days - 9

    Hours - 208

    Minutes - 12,459

    Step-by-step explanation:

    For minutes,

    747,533 : 60 = 12,458.883 ≈ 12,459 minutes

    For hours,

    60 minutes to pass an hour so, 60 * 60 = 3600 minutes

    747,533 : 3600 = 207.648 ≈ 208 hours

    For days,

    1 day = 24 hours

    1 hour = 3600 beats

    24 * 3600 = 86400

    747,533 : 86400 = 8.652 ≈ 9 days
