2) After exercising, two students checked their pulses to see how fast their hearts were beating. Bobby's heart beat 13 times in 10 seconds. Dean's heartbeat 18 times in 15 seconds. a) Compare their heart rates by expressing them using the same unit of time. How many more times would Bobby's heart beat in a minute than Dean? Show all work. b) Maddie measured her heart rate at 12 beats in 10 seconds and then again at 74 beats in 60 seconds. Are these measures equivalent? If not, which do you think is more reliable? Explain.
