On a new construction site, an electrician can install a new light fixture in 20 minutes. A project calls for 24 new fixtures to be installed on each of 4 floors. If a work day is 8 hours, how many work days will it take two electricians to complete the installations?



Answer :

20 minutes per fixture.
24 fixtures per floor. = 20*24 = 480 minutes per floor
4 floors. = 1920 minutes total.
1920 minutes = 32 hours (divide by 60)

32 hours/2 electritians = 16 hours per person
16 hours per person/8 hours per work day = 2 work days.
