The total time taken by the computer would be 2.25 X 10⁻³s
Explanation:
A computer can perform an addition operation in 1.5 X 10⁻⁶ s
Number of addition = 1500
Total time, t = ?
Total time taken = 1500 X 1.5 X 10⁻⁶s
t = 2250 X 10⁻⁶s
t = 2.25 X 10⁻³s
Therefore, total time taken by the computer would be 2.25 X 10⁻³s
