$H=120p+60$
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 $p=0$, Alice has a resting heart rate. When $p=1$, 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?
Difficulty: Medium
A:
$120\leq H\leq 162$
B:
$102\leq H\leq 120$
C:
$60\leq H\leq 162$
D:
$60\leq H\leq 102$
