Question

Person A can paint the neighbors house 2 times as fast as Person B. The year A and B worked together, it took them 2 days. How long would it take each to paint the house.

Answer 1

A can paint in 3days and B in 6 days

Explanation:

From the question we were told

Person A can paint the neighbors house 2 times as fast as Person B

Let A only paint the neighbors house in X days

Let B only paint the neighbors house in 2X days

If we express the given information from the question in terms of fraction we have,

1/X + 1/2X = 1/2

3/2X = 1/2

if we cross multiply we have

6= 2X

X= 6/2

X= 3

Then A can paint the house in 3 days and B in 2(3)= 6days.
