The speed of light is 3.0×108 m/s and the speed of sound is 3.4×102 m/s. Find the value of the integer N in the following statement: If you start counting seconds when you see something happen and stop when you hear it happen, then the event is about 1km away for every N seconds counted.I'm a little confused on how to work this. I think that I should start by converting m/s into km/s, but after that I've got nothing! Thanks in advance!
