An average person's heart beats about 103,680 times a day. write and solve an equation to find about how many times the average person's heart beats in one minute.

It should be noted that in each day there are 24 hours which in turn is comprised of 60 minutes each. The way to answer this item to properly do the conversion and the dimensional analysis.
  1. The equation that would be used in order to find out how many beats in one minute does an average human's heart do is,
                x = (103,680 times/day)(1 day/24 hours)(1 hour/60 minutes) Simplifying,
                x = 72 times / minute

Is there a picture of a graph or whatever that goes along with this?
