Question
The concentration of a medication in the plasma changes at a rate of \( h(t) \) mg/ml per hour, \( t \) hours after the delivery of the drug.

(a) Explain the meaning of the statement \( h(1) = 43 \).

\[ \boxed{\text{1}} \] hour after the drug is administered the concentration of the medicine in the plasma is increasing at a rate of \[ \boxed{\text{43}} \] mg/ml per hour.

(b) There is 190 mg/ml of the medication present at time \( t = 0 \) and

\[
\int_0^3 h(t) \, dt = 480.
\]

What is the plasma concentration of the medication present three hours after the drug is administered?

\[ \boxed{\text{670}} \] mg/ml.
