A fan at a baseball game is 100.0m from the home plate. If the speed of sound is 350 m/s , how long after the batter actually hits the ball does the fan hear the crack? Assume that there is no wind.

Answer 1

distance = speed * time

time = 100/350

Answer 2

PS
about 5 seconds per mile in air is the rule we use navigating at sea. (time between seeing light and hearing horn if they are actuated together.)
