To find the heart rate in beats per second, we need to divide the number of beats by the number of seconds.
There are 60 seconds in 1 minute. So, in 3 minutes, there are 3 * 60 = 180 seconds.
Antonio's heart beats 255 times in 180 seconds.
To find beats per second, we divide the number of beats by the number of seconds:
255 beats / 180 seconds = 1.42 beats per second
Therefore, the answer is C. 1.42 beats per second.
