In a race, if a dog going 37 mph gets a headstart of 12 yards, how long will it take a dog going 38 mph to catch up?
\n" ); document.write( "-----------
\n" ); document.write( "The difference in speed is 1 mi/hr = 22/15 ft/sec
\n" ); document.write( "12 yds = 36 ft
\n" ); document.write( "---------
\n" ); document.write( "d = r*t
\n" ); document.write( "t = d/r = 36/(22/15) = 270/11 seconds
\n" ); document.write( "~ 24.5 seconds
\n" ); document.write( "-----------------
\n" ); document.write( "Note that the time would be the same if the speeds are both >0 and differ by 1 mi/hr.
\n" ); document.write( "
\n" );
