Answer:

166 bpm

Step-by-step explanation:

Ian's age = 60

MHR stands for maximum heart rate. There are two methods of calculating the MHR :

1) MHR = 220-age

2) MHR = 217-(0.85×Age)

Both the methods are easy to solve but the most accurate is the second one, hence we use the second method to calculate MHR of Ian.

MHR = 217-(0.85×Age)

= 217-(0.85×60)

166

Since the MHR is calculated in beats per minute (bpm)

Therefore, MHR of Ian = 166bpm
