If, in a baseball game, a single picher can decide to throw either a 100mph fastball or 60 mph knuckleball on any pitch, how much less time, in seconds, does the batter have from when the ball is released as a fastball than when the ball is released as a knuckle ball? (Assume where the batter's point of contact is exactly 60ft away from the pitcher's release point. 5280 ft = 1 mile.) Pick one
A) 6/22s
B) 7/22s
C) 8/22s
D) 9/22s
E) 15/22s
One conversion to know is = 1 mile = 5280 ft   Time taken for fastball = (60 / (100 * 5280)) * 60 * 60 = 9/22   Time taken for knuckle ball = (60 / (60 * 5280)) * 60 * 60 = 15/22   Qn is the difference between the time taken by the two balls =&gt; 15/22 - 9/22 = 6/22   Option 6/22s
