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 • Find the LCD • Multiply every term by the LCD/1 • Solve for the variable
Example of Work Problem • Nolancan eat a bag of popcorn in 2 minutes. Madisoncan eat a bag of popcorn in 3 minutes. If Nolan and Madisongo to the movies together and share a bag of popcorn how long will it take them to finish? Nolan (worker A) = 2 minutes Madison (worker B)= 3 minutes Together (C) = x minutes
D=RT Steps • Create a chart for d =rt • Solve for the variable that is the same for both parties • Set the equations equal to each other
Example of D=rt • Kylie and Peyton are going to do a flash mob. 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 flash mob at the same time)
