How many nanoseconds does it take for a computer to perform one calculation if it performs $6.7 \times 10 ^ { 7 }$ calculations per second?
A)15 ns
B)67 ns
C)11 ns
D)65 ns

Question

Quizplus · Accepted Answer

To find the time per calculation, take the reciprocal of the calculations per second: $1 / (6.7 \times 10^7)$ seconds per calculation. Converting seconds to nanoseconds (1 second = $10^9$ nanoseconds), we get approximately 15 ns per calculation.
