One painter can paint an entire house in 8 hours. How many hours would it take for three painters to paint the entire house together? is it: a.) 2 hours b.) 2 hours and 40 minutes c.) 3 hours
One painter can paint the entire house in 8 hours. The rate at which the painter paints is 1/8. If three painters are painting the house the rate at which they paint the house is 3*(1/8) = 3/8.
The number of hours they need to paint the house is 8/3 hours = 2 hours 40 minutes.
The correct option is B, 2 hours and 40 minutes
