The average number of heartbeats per second can be found by dividing the total number of heartbeats by the total time.
From the graph, we can see that the total number of heartbeats is 18 and the total time is 12 seconds.
Therefore, the average number of heartbeats per second is 18 divided by 12, which is 3 beats per second.
Use the image to answer the question.
A graph shows an x-axis representing time in seconds ranging from 0 to 12 in increments of 2. The y-axis represents heartbeats ranging from 0 to 18 in increments of 3. The graph shows a line representing resting heart rate. The line passes through the following plotted points: left parenthesis 4 comma 6 right parenthesis; left parenthesis 6 comma 9 right parenthesis; left parenthesis 10 comma 15 right parenthesis; and left parenthesis 12 comma 18 right parenthesis.
