distance=rate*time
Jill can paint 1 house in 5 hours. 1=r*5 r=1/5 houses/hour
Tom can paint 1 house in 4 hours. 1=r*4 r=1/4 houses/hour
1 house = 1/5*x+1/4*x
1=(4x+5x)/20
20=9x
x= 2.2 repeating hours (2 hours, 13 minutes, 20 seconds)

Delbert can paint a fence by himself in 11 hours and Dorothy can paint the same fence in 12 hours How long will it take them to paint the fence if they work together?
Delbert can paint the fence in 11 hours so in 1 hour Delbert paints 1/11 of a fence. Similarly, in 1 hour Dorothy paints 1/12 of a fence. So together, in 1 hour they paint 1/11 + 1/12 = 12/132 + 11/132 = 23/132 of a fence. So to paint the fence together they would need 1 / (23/132) = 132/23 hours = 5.74 hours

In one hour Sally paints one quarter and John paints one sixth, between them they paint five twelfths per hour so would take 2 hours 24 minutes if they worked together. But have you ever known a male and a female to work harmoniously together? Allow at least three hours!

If Joe can paint a house in 3 hours and Sam can paint the same house in 5 hours how long does it take for them to do it together?
Joe can paint the house in 3 hours so Joe paints 1/3 house in an hour. Similarly, Sam paint 1/5 of the house in one hour. So together (assuming no synergy) they paint 1/3 + 1/5 = 8/15 of the house in an hour. So they take 15/8 = 1 + 7/8 = 1.875 days to paint it.

The way you calculate this (assuming that both work at constant speed) is:* Calculate what part of the house each person can paint in an hour. * Add both fractions together, to calculate what part of the house you can paint together. * Take the reciprocal of this last result, to calculate the number of hours.
