The answer & explanation for this question is given in the attachment below.
Answer:
The overall speedup gained by incorporating the enhancement is 1.563
Explanation:
Using Amdahl's Law;
The overall speedup 
where;
P = Fraction Enhanced for Old Processor
n = speedup enhancement as a result of the new processor
P = 40% = 0.40 and n = 10
∴
The overall speedup (N) is:



= 1.563
Thus, the overall speedup gained by incorporating the enhancement is 1.563
