How many nanoseconds does it take for a computer to perform one calculation if it performs 6.7x10⁷. Calculations per second? A)15 ns B)67 ns C)11 ns D)65 ns

Question

Quizplus · Accepted Answer

To find the time it takes for one calculation, you take the reciprocal of the calculations per second. Given 6.7x10^17 calculations per second, the time per calculation is 1/(6.7x10^17) seconds. Converting seconds to nanoseconds (1 second = 1x10^9 nanoseconds), the calculation is (1/6.7) x 10^(-17+9) = (1/6.7) x 10^(-8) ≈ 0.15 x 10^(-7) = 15 nanoseconds.
