Contain a variety of problems. Use a rational equation to solve each exercise. If one pipe can fill a pool in $a$ hours and a second pipe can fill the pool in $b$ hours, write a formula for the time, $x,$ in terms of $a$ and $b,$ for the number of hours it takes both pipes, working together, to fill the pool.
Use a rational equation to solve. Each exercise is a problem involving work. A pool can be filled by one pipe in 6 hours and by a second pipe in 12 hours. How long will it take using both pipes to fill the pool?
