The Target heart rate for fit person of age a exercising at p percent of his or her heart rate is determined by the expression 1/2p(418-4) for women and 1/2p(400-a) for men. What is the difference between the target heart rates for fit woman in a fit man?

9p - 1.5a

Step-by-step explanation:

Your maximum heart rate is about 220 minus your age. But it varies base on age category.

Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate.

According to the question;

Target heart rate for

women = 1/2p(418-4a)

= 209p - 2a (1)

men = 1/2p(400-a)

= 200p - 0.5a (2)

To find the difference between the target heart rates for a fit woman and a fit man, take equation 1 from equation 2

(209p - 2a) - (200p - 0.5a)

209p - 2a - 200p + 0.5a

9p -1.5a
