### Suggested Learning Targets

**Rational Function Applications**

Examples:

1. Stephanie can jog 5 miles downhill in the same time it takes her to jog 3 miles uphill. She jogs downhill 4 mph faster than she jogs uphill. Fins her jogging rate each way.

2. Adrian can weed the garden twice as fast as his son, Phlilip. Together, they can weed the garden in 3 hours. How long would it take each of them working alone?**Word Problems with Rational Equations**

How to solve word problems involving rational equations, such as work problems?

Examples:

1. Sandra can paint a kitchen in 6 hours and Roger can paint the same kitchen in 7 hours. How long will it take for both working together to paint the kitchen?

2. Together, Naomi and Kenyu can write a particular type of computer program in 17 hours. Alone, Naomi can do the job 3 hours faster than Kenyu. Find the time that each person takes to write a computer program.**Rational Equations Word Problems**
