You are correct C. is the answer.
Answer:
It takes 46 minutes for 10 people to paint 3 walls
It takes 92 minutes for 10 people to paint 6 walls (twice as long because you have twice as many walls)
You only have 4 people to paint the walls instead of 10 people
Therefore it will take 2.5 times as long (10/4=2.5)
2.5*92=230 minutes
10^5 is equivalent to 100,000. I hope this answers your question and I hope you have a great day ! :)
3 3/4 divide 2 1/12 = 1.8
