Question 928281
The "he hit a ball 245.7 feet" bit of info is irrelevant because we don't know any of the throwing speeds of the outfielders or the basemen. We also don't know anything about how fast the ball is flying out and how long it takes to land. So we'll ignore that part.


So let's just assume he runs 19 mph and he runs 90 ft. How long does it take? Well let's find out.


-------------------------------------------------------------------------


90 ft * (1 mi/5280 ft) = 90/5280 = 0.017045 miles


90 ft = 0.017045 miles approximately


-------------------------------------------------------------------------


d = r*t


0.017045 = 19*t


0.017045/19 = t


0.000897 = t


t = 0.000897


The approximate time in hours is 0.000897. Let's convert to seconds


0.000897 hours * (60 min/1 hr)*(60 sec/1 min) = 0.000897*60*60 = 3.2292


Keep in mind that much of these calculations are approximate. 


So it takes roughly <font color="red">3.2292 seconds</font> for the batter to run 90 feet. This is assuming the batter maintains a speed of 19 mph.
