Did you try using the technique of units cancellation?  If so, what did you obtain for answers?

As for problem a) I used unit cancellation and got (10,714mg/960min). Do I now divide 200 by this rate to find how many minutes it takes to metabolize the drug?

Can you show your calculation?  I don't see how you got there.
