10.7 Solving Rational Equations in Word Problems -Work Problems -D=RT Problems
Work Problems A is worker a B is worker b C is worker a and b working together
Steps to Solve 1.Find the LCD 2.Multiply every term by the LCD/1 3.Solve for the variable
Example of Work Probelm Gavin can eat a bag of popcorn in 2 minutes. Ashlynn can eat a bag of popcorn in 3 minutes. If Gavin and Ashlynn go to the movies together and share a bag of popcorn how long will it take them to finish?
D=RT Steps 1.Create a chart for d =rt 2.Solve for the variable that is the same for both parties 3.Set the equations equal to each other
Example of D=rt Kylie and Ella are going to see Justin Bieber in concert. Kylie lives 1 mile away and Ella lives 5 miles away. What speed do they need to travel if they leave at the same time given that Kylie walks and Ella runs 10 mph faster then Kylie? (They want to meet at the concert at the same time) Drt Kylie Ella
