If an average person produces 2 million red blood cells per second, how many red blood cells will be produced in a 24 hours period

I believe the answer is 172,800,000,000 per day (24 hours)

How I Got That

I calculated 2 million times 60

=120000000 per minute

Then I calculated that times 60 again

=7200000000 per hour

Then I calculated that times 24

=172800000000 per day

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
