    Answer: 0.145 seconds

    Explanation:

    Given that Roger Clemens could routinely throw a fastball at a horizontal speed of 119.7 m/s. How long did the ball take to reach home plate 17.3 m away

    Since the speed is horizontal

    Using the formula for speed which is

    Speed = distance/time

    Where

    Speed = 119.7 m/s

    Distance covered = 17.3 m

    Time is what we are looking for

    Substitute all the parameters into the formula

    119.7 = 17.3/ time

    Make time the subject of formula

    Time = 17.3 / 119.7

    Time = 0.145 seconds.

    Therefore, it will take 0.145 seconds to reach the home plates
