Question 434622
ryan can paint a fence in ten hours. asanji can paint the same fence in eight hours. if they worked together how long would it take them.
.
Let x = time (hours) it takes for both
then
x(1/10 + 1/8) = 1
multiplying both sides by 80:
x(8 + 10) = 80
18x = 80
x = 80/18
x = 4.44 hours
or
x = 4 hours and 27 minutes
