If the pitcher throws the ball at 80 miles/hour, how long does it take the ball to reach home plate?
speed= distance /time
now speed of ball is given 80 miles/hour = 128748 meter/hour
distance(in this case not given , so i will take it as standard distance)=18.44 meter
time= diistance/speed = 18.44/128748 hrs = 0.5156 seconds
