<PRE><B>Question 210517</B>
Fastball thrown by.....travels at a speed of 145km/hr toward the batter who is 18.3 meters away. How long does it take the baseball to travel this distance.
----------------------------------------
Distance divided by Rate = Time
145 km/hr = 145000 meters per hour
----------------------------------------
Equation:

18.3m / 145000 m/hr = 0.0001262...hrs
----
Change to seconds:
0.0001262 hrs = 0.0001262*3600 seconds = 0.4543 seconds
