Question

Andrew can paint the​ neighbor's house 5 times as fast as Bailey. The year Andrew and Bailey worked​ together, it took them 2 days. How long would it take each to paint the​ house?

Answer 1

12 days for Bailey

2.4 days for Andrew

Explanation:

If Andrew is 5 times as fast, then Andrew + Bailey are 6 times as fast as Bailey alone.

That means Bailey would take 2*6 = 12 days to paint alone.

Since Andrew is 5 times faster, he'd only take 12/5 = 2.4 days.
