Answer:
15 hrs.
Step-by-step explanation:
Wouldn't it be 15 hours, if the other painter finished in 15 hours? They can finish the house in 10 hours together, but if you split the 10, that would be 5 for both of them. Then you would add the 5 hrs. to the original 10 hrs. that the both of them had worked, and act as if it was one person.
Hope this helps! (:
The number of hours taken by the second painter for finishing the house working alone is 30 hours.
Given that,
Based on the above information, the calculation is as follows:
[tex]= \frac{1}{10} - \frac{1}{15} \\\\= \frac{3 - 2}{30} \\\\= \frac{1}{30}[/tex]
= 30 hours
Therefore we can conclude that the number of hours taken by the second painter for finishing the house working alone is 30 hours.
