The Karvonen formula above shows the relationship between Alice’s target heart rate H, in beats per minute (bpm), and the intensity level p of different activities. When p equals 0, Alice has a resting heart rate. When p equals 1, Alice has her maximum heart rate. It is recommended that p be between 0.5 and 0.85 for Alice when she trains. Which of the following inequalities describes Alice’s target training heart rate?

A.

120 is less than or equal to H, which is less than or equal to 162

B.

102 is less than or equal to H, which is less than or equal to 120

C.

60 is less than or equal to H, which is less than or equal to 162

D.

60 is less than or equal to H, which is less than or equal to 102
