An animal breathes approximately 25 times per minute.
part a: about how many seconds would it take to breathe one million times?
part b: how many minutes would it take to breathe one million times?
part c: how many hours would it take to breathe one million times?
part d: how many days would it take to breathe one million times?
part e: how many years would it take to breathe one million times?

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

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
