SAMPLE ALGEBRA QUESTION:
If Sally can paint a house in 4 hours, and John can paint the same house in 6 hour, how long will it take for both of them to paint the house together?
2 hours and 24 minutes
3 hours and 12 minutes
3 hours and 44 minutes
4 hours and 10 minutes
4 hours and 33 minutes
First of all Sally should not be painting the house to begin with, it's just gonna aggravate her sciatica. And like John is actually going to help Sally with any work around the house much less painting the whole thing! John was never right after hitting his head when he fell off that mechanical bull.
So the answer is, Sally should call the painter. See, math is dumb.
