Let x be Joanna's heart rate immediately after running one mile. After this heart rate x decreased by 2 over 5, Joanna's heart rate was 60 beats per minute. We can set up an equation to solve this question. x - (2/5) x = 60 (3/5) x = 60 x = (5/3) 60 x = 300 / 3 x = 100 Joanna's heart rate immediately after running one mile was 100 beats per minute.
