Its B no doubt
cuz ik how to do this i took classes for this so ik im right ight
<span>At lower speeds modulating speeds is a must for safety. I would be hard pressed to find a place in town you could drive 25 mph for an extended time. Also, plan on a lot of shifting at lower speeds. That completely negates using the cruise on a manual and really puts the auto in the hunting mode. I would think it safer that you move the selector into a lower gear to get some engine braking at say, 25 mph which would make it easier to sustain the speed rather then use the cruise.
Brainliest please?</span>
Answer:
Check the explanation
Explanation:
CPI means Clock cycle per Instruction
given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M
Execution time is given by following Formula.
Execution Time(CPU time) = CPI*Instruction Count * clock time = 
a)
for system A CPU time is 1.3 * 100, 000 600 106
= 216.67 micro sec.
b)
for system B CPU time is 
= 333.33 micro sec
c) Since the system B is slower than system A, So the system A executes the given program in less time
Hence take CPU execution time of system B as CPU time of System A.
therefore
216.67 micro = =
Instructions = 216.67*750/2.5
= 65001
hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A
