If the cannon is seen to fire six seconds before the shot is heard, the cannon is just over 1900 metres (about 2100 yards) from the observer.
Using the speed of sound at 20° C, which is 343 m/sec, the cannon would be 2058 meters away. Temperature, pressure, and humidity could all affect the actual speed.
So, the sound travels at about 340 meters per second. The answer is 340 meters X 5 seconds equals 1700 meters away is the lightning strikes.
Cannonballs were invented around the same time as the cannon which was around the 1600's. They were used as weapons that could be fired from a safe distance to keep away enemies.

Two metres per second !
The iceberg is 1372 meters away.
You shoot a cannon with a vi of 18 m/s. You need to get it 16m and over a 10m wall. The acceleration in the x is 0 and in the y it is gravity. The question is at what angle theta can you shoot the cannon over the fence and 16 meters away. How do I find theta?
~400 meters effective range (Lethal and predictive) ~900 meters Firing range ( CAN be lethal from 400 to 900 m) ~2000 meters maximum range (maximum range the bullet can travel away - fired in a 45 degree angle)
roughly, just under four seconds if you'r really lazy. 3.9 secs to round off. i'd say 3.864516129032258 seconds
Oswald was 85 feet away from Kennedy when he fired the fatal shot. The other shots' range are unknown.
You travelled at an average speed of 2 metres per second.
