It's #8//3~~2.7km#

At distances like this the time it takes light to travel can be left out of the equation, because it's extremely short - less than #1//100000# of a second.

Sound travels at between #330-340m//s#, depending on temperature, air pressure and humidity (and direction of wind), so #1//3# of a km is a reasonable estimate.

Answer : divide time (seconds) by three to get distance (km)
(divide by five to get miles)
