To define a variable for the number of times your heart beats in a minute, let's call it "heart_beats_per_minute."
To calculate the number of times your heart beats in a minute, we need to consider that in a given 15-second interval, you count the number of heartbeats. We'll call this variable "heart_beats_in_15_seconds."
Since there are 60 seconds in a minute, we can calculate the number of heartbeats per minute using the following expression:
heart_beats_per_minute = 4 * heart_beats_in_15_seconds
This expression multiplies the number of heartbeats counted in 15 seconds by 4. This is because there are four times 15 seconds in a minute (60 seconds).
Once you determine the value for "heart_beats_in_15_seconds" by counting your heartbeats, you can substitute that value into the expression to find the total number of heartbeats per minute.
