HELP ME PLZZZZZ
If 3 workers can paint a room in 3 hours, then approximately how long does it take 4 workers to paint the same room? Assume the time needed to paint the room is inversely proportional to the number of workers.

Answer 1

im soo stumped on this one

Answer 2

3 Workers=3Hours? , So 4Workers=2Hours

Answer 3

that doesnt seem right

Answer 4

becasue the 4 workers r working in the same room the 3 workers did

Answer 5

ok ....
the work done by 3 workers can be said as
3 workers x 3 hours = 9 units
so the total work can be said as 9 units...

now if there is 9 units of work to done and u ve got 4 workers ....
the time = the amount of work / no. of workers
= 9/4
= 2.25 hours
got it :) ?
