Problema Solution
you and a group of friends volunteer to help paint a house. you need to paint four rooms in eight hours. if each person can paint one room in 10 hours, how many people will it take to paint all of the rooms on time
Answer provided by our tutors
the rate of one person is 1 room in 10 hours = 1/10 rooms/hour
the rate of x people is x/10 rooms/hour
lets say that x people can paint 4 rooms in 8 hours thus we have
x/10 = 4/8
x = 10*(4/8)
x = 5 people
it takes 5 people to paint four rooms in eight hours.
