Question 323259: Could you please help me figure out the answer to this word problem?
If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take for both of them to paint the house together?
A. 2 hrs and 24 mins
B. 3 hours and 12 mins
C. 3 hours and 44 mins
D. 4 hours and 10mins
E. 4 hours and 33 mins.
I thought that the way to get the answer would be to add both times together (4+6=10) and divide by two (the number of people painting), to get 5hrs as the answer. Apparently this is not correct, since 5 hrs is not one of the answers.
Thanks for helping.
