Problem $2$: $[5$ points$]$ Suppose you have a machine that executes a program consisting of $50\%$ floating point multiply, $20\%$ floating point divide, and the remaining $30\%$ are from other instructions. Management wants the machine to run $4$ times faster. You can make the divide run at most $8$ times faster and the multiply run at most $10$ times faster. Can you meet management$$s goal by making only one improvement, and which one?
