Answer:
In 3 weeks, you take 181440 breaths.
Explanation:
1. Set up a rule of 3.
10 seconds ----> 1 breath
3 weeks --------> x
2. Convert 3 weeks into seconds.
3 weeks * 7= 21 days
21 days * 24= 504 hours
504 hours * 60= 30240 minutes
30240 minutes * 60= 1814400 seconds.
3. Rewrite and solve the rule of 3 with the converted units.
10 seconds ------------> 1 breath
1814400 seconds ---> x
x= (1814400 seconds * 1 breath) / 10 seconds
x= 181440 breaths.
4. Express your result.
In 3 weeks, you take 181440 breaths.
