18 year old Bianca ran sprints for 30 seconds as fast as she could run, then checked her pulse abd realized it was 8 beats above her maximum heart rate. What was her heart rate?
A person's estimated maximum heart rate is 220 minus their age. Since she is 18, her maximum is 220 - 18 = 202. As hers was 8 beats over her maximum, simply add 8 to 202 to find 210 as her heart rate.
