I think he defines one operation as a task. It's actually an easy calculation to do.
I typed "speed of light in inches per second" on google to get 1.180285270 * 10^10 in/sec then multiplied this by the amount of time to do one operation which is 1/5000000000 seconds
1.180285270*10^10(in/sec) * (1/5000000000)(sec) = 2.36057054 inches
So this processor can do one operation in the time it would take light to travel 2.36 inches.
The annoying thing is that because of pipelining and many other factors, it is hard to quantitatively determine how much an operation actually is. It isn't like the old processors where you could easily look up how many operations an instruction took and then calculate exactly how long it would take to run a given routine. It all depends on the processor architecture.
