Application / word problems involving rational expressions / fractions.
- How do you solve word problems with rational expressions?
- If one person paints a room in 6 hours, and another person paints the room in 4 hours, how long does it take them if they paint together?
- If one pump drains a pool in 10 hours and another pump drains a pool in 15 hours, how long does it take them together?
A really useful problem is discussed that you see a lot in math classes. Two people are painting a room together, and you have to find out how long it takes them to paint two rooms. A must-see if you want to always remember how to do this problem. The second problem is very similar and works almost the same way.
