9. If a computer can perform an addition operation in 1.5x10 seconds, in how much time can it perform 1500 addition

operations?

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
