  1. 1W = 1J/s. 75W = 75J/s.

    1min. = 60s

    75J/s x 60s = 4,500J (4.5kJ) of work.


  2. yes, I can convert minute to seconds.

    75 watts is 75 joules per second

    75 joules per second x 60 sec/min = 4500 joules of work/energy

    Work/energy can also be expressed as watt-hours

    75 watts x 1 min x 1hr/60 min = 1.25 watt-hr.
