Question 1003739: A nurse must be careful not to inject a drug too quickly into a patient’s IV. If the drug is injected at the maximum rate of 0.1 cc per second, and the total amount to be injected is 30 cc,
a. Create an equation that tells the amount injected as a function of time (in seconds);
b. Determine the time required to complete the injection.

The time in seconds to inject 30 cc at the
maximum rate of +.1+ cc/sec is:
+30+%2F+.1+=+300+ sec
-------------------
Let +t+ = time in sec
+t%2F300+ sec is the fraction of the 30 cc that
gets injected
-------------------
Let +A+ = amount in ccs injected
+A+=+30%2A%28+t%2F300+%29+
+A+=+t%2F10+
--------------
Note tyhat if +t=300+ sec
+A+=+300%2F10+
+A+=+30+
