A new crew of painters takes two times as long to paint a small apartment as an experienced crew. together, both crews can paint
the apartment in 4 hours . how many hours does it take the experience crew to paint the apartment
1 answer:
Answer:
Step-by-step explanation:
Let the inexperienced crew do the apartment in x hours.
Therefore it takes the experienced crew x/2 = 0.5x hours to do the same place.
x + 0.5x = 4 hours
1.5x = 4 hours
x = 4/1.5
x = 2.67 hours.
So the inexperienced crew does the job in 2.67 hours.
The experienced crew can do it 1/2 the time which is 1.335
Total time = 4 hours.
