$H equals, 120 p, plus 60$

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