Final answer:
Corey's heart rate off the ice is 156 beats per minute. For an exercised heart rate of 150 beats per minute, the time per beat is 0.4 seconds.
Step-by-step explanation:
Corey's heart rate after coming off the ice in a hockey game is given as 26 beats in 1/6 minute. To find the heart rate in beats per minute (bpm), we can set up a proportion or use unit conversion. Since there are 6 intervals of 1/6 minute in one full minute, we multiply 26 beats by 6.
26 beats × 6 = 156 bpm.
If her heart rate is 150 beats per minute during strenuous exercise, to find the time per beat in seconds, we divide 60 seconds (which is 1 minute) by 150 to calculate the time per single beat:
60 seconds ÷ 150 beats = 0.4 seconds per beat.
