A student in gym class wants to measure how much his heart rate increases after sprinting 25 feet. The student records his resting heart rate at 12 beats per 10 seconds. After the student sprinted 25 feet, he recorded his heart beat at 130 beats per minute. Calculate the difference in the student’s heart rate (beats per minute) from his initial steady state.
