Question

You are taking the heart rate of a cat. If you count 10 beats in 5 seconds, what is the rate in beats/min?

a) 60 beats/min
b) 90 beats/min
c) 120 beats/min
d) 150 beats/min

Answer 1

To find the heart rate in beats per minute, count the number of beats in a specific time frame, calculate the rate per second, and then multiply by 60. In this case, counting 10 beats in 5 seconds results in 120 beats per minute.

Step-by-step explanation:

If you count 10 beats in 5 seconds when taking the heart rate of a cat, you can calculate the rate in beats per minute by using the following steps:

• First, determine how many beats occur in one second by dividing the number of beats counted by the number of seconds. That is 10 beats / 5 seconds = 2 beats per second.
• Then, since there are 60 seconds in a minute, multiply the number of beats per second by 60 to find the number of beats per minute. This gives us 2 beats per second * 60 seconds per minute = 120 beats/min.

Therefore, the correct answer is (c) 120 beats/min.
