Angie and Lisa were taking gymnastics together. one day each of them ran to class. together it took them 12 3/4 minutes. it took lisa twice as much time as it took Angie. how many minutes did it take each of them to run?
----------------------------------------------
Let Angie time be x minutes, then Lisa = 2x.
Equation:
x + 2x = 12.75 minutes
3x = 12.75
x = 4.25 minutes (Angie time)
2x = 8.50 minutes (Lisa time)
