Answer:
instruction execution time = 5 micro seconds
Step-by-step explanation:
given data:
number of states 20
Clock period is 250 ns
where ns is nano seconds
instruction execution time is given as
instruction execution time = number of states * clock period
putting all value to get required answer
instruction execution time = 250* 20 = 5000 ns = 5 micro second
instruction execution time = 5 micro seconds
