The conversion to nanoseconds is the second step for the question. First you have to find the time for one operation, in seconds or any convenient unit. Then you can convert in nanoseconds.

The given value is not the time for one operation but the number of operation per second.

Alright so I got 14 nano seconds, I did 1 calculation/ seconds * seconds/ calculations per second which was 14 nano seconds :P
