Person A can paint the neighbor's house 6 times as fast as Person B. The year A and B worked together it took them 4 days. How long would it take each to paint the house?

Person A takes 4.66 days and person B 28 days

Step-by-step explanation:

Let t = time required by A to paint the house

"Person A can paint the neighbor's house 6 times faster than Person B."

Thus:

6 * t = time required by person B

Therefore we have to:

4 / t + 4/6 * t = 1

we solve:

(4 * 6 * t + 4 * t) 6 * t * t = 1

(28 * t) 6 * t * t = 1

6/28 = t

t = 14/3

that is, person A takes 4.66 days and person B 28 days (4.66 * 6)
