1. noah estimates that his maximum heart rate is 208 beats per minute. noahs teacher tells him that his target heart rate for physical activity is between 70% and 85% of his maximum heart rate. after running one mile, noahs heart rate is 156 beats per minute. when noah ran one mile, did he meet his target heart rate? explain.

Explanation:

Step1: Calcular el 70% del máximo de latidos

$$208\times0.7 = 145.6$$

Step2: Calcular el 85% del máximo de latidos

$$208\times0.85=176.8$$

Step3: Comparar el latido de Noah con el rango

Noah tiene 156 latidos por minuto. Como \(145.6<156<176.8\), está dentro del rango.

Answer:

Sí, Noah cumplió con su objetivo de frecuencia cardíaca.
