Question

Training Heart Rate. A person's training heart rate, in beats per minute, is the person's resting heart rate plus 60% of the difference between maximum heart rate and his resting heart rate. If resting heart rate is R and maximum heart rate is M, then the formula that gives training heart rate is

Answer 1

We have the following formula:

`T=R+(3)/(5)(M-R)`

Where: T = training heart rate

R = resting heart rate

M = maximum heart rate = 189

Then solve for T, given R:

R = 60

`T=60+(3)/(5)(189-60)=60+(3)/(5)(129)=60+77.4=137.4`

R = 62

`T=62+(3)/(5)(189-62)=62+(3)/(5)(127)=62+76.2=138.2`

R = 64

`T=64+(3)/(5)(189-64)=64+(3)/(5)(125)=64+75=139`

R = 68

`T=68+(3)/(5)(189-68)=68+(3)/(5)(121)=68+72.6=140.6`

R = 70

`T=70+(3)/(5)(189-70)=70+(3)/(5)(119)=70+71.4=141.4`

R = 72

`T=72+(3)/(5)(189-72)=72+(3)/(5)(117)=72+70.2=142.2`
