Answer:
187
Explanation:
A formula often used to calculate the maximum heart rate is:
208 - 0.7 x age
From the value found, it is possible to analyze the working range that we must maintain, according to the prescription of a professional for the physical objective traced. For example, for fat burning aerobic work, the recommendation is to keep your heart rate between 55 and 75% of your maximum heart rate (known as “zone fat burn”).
In Molly's case, when we calculate the maximum heart rate we will give:
208 - 0.7 x 30 = 187
