Step-by-step explanation:
A. Distance = rate × time
1,000,000 breaths = 25 breaths/min × t
t = 40,000 min
One minute is 60 seconds, so:
t = 40,000 min × (60 s / min)
t = 2,400,000 s
B. We already answered this in part A. 40,000 minutes.
C. There are 60 minutes in an hour, so:
t = 40,000 min × (1 hr / 60 min)
t = 666.67 hr
D. There are 24 hours in a day, so:
t = 666.67 hr × (1 day / 24 hr)
t = 27.78 days
E. There are 365 days in a year, so:
t = 27.78 day × (1 yr / 365 day)
t = 0.076 years
