Two painters working together can paint a house in 10 hours working alone the first painter can finish the house in 15 hours how long would it take the second painter to finish the house working alone

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! (:

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
