Answer:
Joe's heart beats approximately 66 times in 60 seconds.
Explanation:
To find out how many times Joe's heart beats in 60 seconds, we can set up a proportion using the given information.
Let's define the following variables:
x = number of heart beats in 60 seconds
We know that Joe's heart beats 11 times in 10 seconds. We can set up the proportion:
11 beats / 10 seconds = x beats / 60 seconds
To solve this proportion, we can cross multiply:
10 * x = 11 * 60
10x = 660
Divide both sides of the equation by 10 to isolate x:
x = 660 / 10
x = 66
