Answer 2

Explanation:

It is given that Todd is 30 year old and he perform aerobic activity that may increase his heart beat.

=220-30=190

And during exercise his heart beat increases to 60-90 % of maximum value

60 % of 190=114 beats/min

90 % of 190=171 beats/min

So Heart beat can goes up to 114 - 171 beats/min
