One of the fastest pitches ever thrown in Major League Baseball was by Aroldis Chapman and had a velocity of 105.1 miles/hour. How many seconds did it take this pitch to travel the 60 feet and 6 inches from the pitcher's mound to home plate

t = 0.39 s

Explanation:

Assuming that the ball is launched horizontally, once in the air, if we neglect the resistance of the air, the ball moves at a constant speed, equal to the initial velocity, in this case, 105.1 mi/hr.In order to find time in seconds, it is advisable to convert the speed in mi/hr to m/s, as follows:

       

In the same way, it's advisable to convert 60' 6'' (60.5') to m, as follows:

       

Applying the definition of average velocity, we can find the time traveled by the ball from pitcher's mound to home plate, as follows:
