Answer: 0.87 times per second (Or 52.2 times per minute)
Step-by-step explanation:
You need to make the conversion from minutes to seconds.
Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:
![(20minutes)(\frac{60seconds}{1minute})=1,200seconds](https://tex.z-dn.net/?f=%2820minutes%29%28%5Cfrac%7B60seconds%7D%7B1minute%7D%29%3D1%2C200seconds)
Find the number of times the heart beats in 1 second when it is rowing:
![x_1=\frac{(2,320times)}{1,200seconds}=1.93\ times\ per\ second](https://tex.z-dn.net/?f=x_1%3D%5Cfrac%7B%282%2C320times%29%7D%7B1%2C200seconds%7D%3D1.93%5C%20times%5C%20per%5C%20second)
Find the number of times the heart beats in 1 second when it is resting:
![x_2=\frac{(16times)}{15seconds}=1.06\ times\ per\ second](https://tex.z-dn.net/?f=x_2%3D%5Cfrac%7B%2816times%29%7D%7B15seconds%7D%3D1.06%5C%20times%5C%20per%5C%20second)
Then the difference is:
![difference=(1.93-1.06)\ times\ per\ second\\difference=0.87\ times\ per\ second](https://tex.z-dn.net/?f=difference%3D%281.93-1.06%29%5C%20times%5C%20per%5C%20second%5C%5Cdifference%3D0.87%5C%20times%5C%20per%5C%20second)
(Or 52.2 times per minute)
