Ping time

Calculate the theoretical ping time between Orlando and Shenzhen, which is 14102 km distant. Ping time measures the round-trip time for small messages sent from the origin to a destination that is echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects underwater.

Assume that signal travel in optic cable - speed of light in a fiber optic cable (200,000km/s).

Correct answer:

t =  141.02 ms

Step-by-step explanation:

d=2 14102=28204 km v=200000 km/s  t1=d/v=28204/2000000.141 s t=1000 t1=1000 0.141=141.02 ms
