D) 11 ns

Question

Quizplus · Accepted Answer

To find the time it takes for one calculation, divide 1 second (or 1,000,000,000 nanoseconds, since there are 1 billion nanoseconds in a second) by the number of calculations per second. Thus, 1,000,000,000 ns / 6.7 × 10^7 calculations = approximately 15 ns per calculation.
