Question

A persons resting heart rate is typically between 60 and 100 beats per minute. Noah looks at his watch, and counts 8 heartbeats in 10 seconds.

Is his heart rate typical? Explain how you know.

Write an equation for h, the number of times Noahs heart beats (at this rate) in m minutes.

Answer 1

Answer:

it is not typical

Step-by-step explanation:

Every 10 seconds, Noah's heart beats 8 times.

Therefore, every 1 minute, his heart beats 48 times.

Noah's heartbeat is below a typical person's resting heart rate.

there would have to to be 10 heart beats for his heart beat to be typical!

which concludes that Noah's heart rate is not typical

Answer 2

In 60 seconds his heart will have beat 48 times, so his heart rate is not typical.

A person's resting heart rate is typically between 60 and 100 beats per minute, and Noah looks at his watch, and counts 8 heartbeats in 10 seconds.

To determine if his heart rate is typical, the following cross multiplication calculation must be performed:

A cross multiplication should be considered to determine the value of his beats in 60 seconds at the same rate that his heart has been beating.

• 10 = 8
• 60 = X
• 60 x 8/10 = X
• 480/10 = X
• 48 = X

Thus, in 60 seconds his heart will have beat 48 times, so his heart rate is not typical.
