so the total amount of hours is 42 × 5,
after 2 works, hours is 42 × 2
remaining time is (42×5)-(42×2)
42 - 28 = 14 remaining people
so time took = [ (42×5)-(42×2) ] / 14
so they start at 4pm
then the 2 hours
then the remaining time took
which is 3 am
which is 5 hours after 10pm
it's just problem solving
just have to follow your nose so to say
and just try things
