B or d are most likely it I could be wrong if I am, I am so sorry:)
See the file attached and let me know whether you understand the explanation.
Time for p1 to execute the instructions is
.. (4.2*10⁹ i)*(1.6 c/i)/(3.0*10⁹ c/s) = 2.24 s
Time for p2 to execute the instructions is
.. (4.0*10⁹ i)*(2.00 c/i)/(3.5*10⁹ c/s) = 2.29 s
Processor p1 is faster by about 2%.
<span>The
problem said that for each part, there is 1/10 mile long. If Marsha finished 5
parts of the race, just multiply 5 by 1/10 and you will get 5/10 or ½ or 0.5
miles. Therefore, Marsha finished 0.5 miles of the race.</span>
