In a game against the White Sox, baseball pitcher Nolan Ryan threw a pitch measured at 34.4 m/s. If it was 18.4 m from Nolan's position on the pitcher's mound to home plate, how long did it take the ball to get to the batter waiting at home plate? Treat the ball's velocity as constant and ignore any gravitational effects.
since time = distance/speed,
just divide the distance by the speed.
