1. One painter can paint an entire house in four hours. A second painter takes two hours on his own . If they paint the same house at the same time, how long would it take the two painters to paint one house?
.
Let t = time (hours) it takes for both
then
t (1/4 + 1/2) = 1
t (1 + 2) = 4
t (3) = 4
t = 4/3 hours
or
t = 1 hour and 20 minutes
