1. Suppose that a given optimization results in an OVERALL speedup of 2 over the original design. If the optimization speeds uploads and stores, which collectively accounted for 75% of the execution time BEFORE the optimization, by what factor were loads and stores sped up by the optimization?

2. If, in problem 1, the described optimization could make loads and stores take no time at all (not realistic, just for the sake of argument), what would the overall speedup to the execution time be?

PLEASE ANSWER 1 and 2
