Joanna ran a mile in physical education class. After resting for one hour, her heart rate was 60 beats per minute. If her heart rate decreased by /5, what was her heart rate right after running a mile?

Respuesta :

60/5= 12

Heart rate = 60 - 12= 48
48 because you would divide 60 by 5 and get 12 and subtract 12 from 60 and get 48
