Question

A computer program in Shannon’s computer carries out a single mathematical operation in 1.5 × 10-6 seconds. How much time would the program take to complete 2.5 × 103 mathematical operations?

Answer 1

1/1.5 * 10^-6 = 2500/x
x = 1.5 * 10^-6 * 2500
x = 0.00375 or 3.75 * 10^-3 second.
Good question. 

Answer 2

You forgot A, B, C, and D but the correct answer is option D, 3.75 x 10 ^ -3 seconds
