Question

Find the heart rates of you and your friend. Your heart rate is beats per second. Your friend's heart rate is beats per second. Question 2 Do these rates form a proportion? Explain. Yes, the rates have the same units. Yes, the rates are equivalent. No, the rates have values greater than 1. No, the rates are not equivalent.

Answer 1

Your heart rate is 1.1 beats per second. Your friend's heart rate is 1.2 beats per second. Yes, the rates have the same rate (bps).

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction. The heart rate is calculated by the following formula as:

The heart rate = The number of heartbeats / The number of seconds

As per the given data, the required solution would be as:

Your heartbeat = 22:20

Your heartbeat = 22/20

It can be reduced to 11/10

Your heartbeat = 11/10

We then apply the division operation, and we get

Your heartbeat = 1.1 bps

Friend's heartbeat = 18:15

Friend's heartbeat = 18/15

It can be reduced to 6/5

Friend's heartbeat = 6/5

Friend's heartbeat = 1.2 bps

In conclusion, the rate of your heart is 1.1 beats per second. The heart rate of your friend is 1.2 beats per second.

Hence, the rates are the same (bps).

Answer 2

yes, the rates have the same units
