Answer:

  • See below

Step-by-step explanation:

Make proportions and solve

When Julie finished 1 lap, how many laps had Joe run?

  • 3/9 = 1/x ⇒ x = 9/3 = 3 laps

When Julie finished 9 laps, how many laps had Joe run?

  • 3/9 = 9/x ⇒ x = 9*9/3 = 27 laps

When the total number of laps that Julie and Joe have completed is 16, how many of those laps were Joe’s, and how many were Julie’s?

  • 3x + 9x = 16
  • 12x = 16
  • x = 16/12
  • x = 4/3

Julie's laps:

  • 3*4/3 = 4 laps

Joe's laps:

  • 16 - 4 = 12 laps
