3. Consider a computer running a program that requires 250 s, with 70 s spent executing FP instructions, 85 s executed L/S instructions, and 40 s spent executing branch instructions. 3.1 By how much is the total time reduced if the time for FP operations is reduced by 20%? (2 points) 3.2 By how much is the time for INT operations reduced if the total time is reduced by 20%? (2 points) 3.3 Can the total time can be reduced by 20% by reducing only the time for branch instructions? (2 points) 3.
