A car 15 feet long overtakes a truck 30 feet long which is traveling at
\n" ); document.write( "a rate of 45 miles per hour.
\n" ); document.write( "How fast must the car travel to pass the truck in 3 seconds?
\n" ); document.write( ":
\n" ); document.write( "The car has to cover the sum of the lengths of the car and the truck (at least)
\n" ); document.write( "to pass, which is 45 ft
\n" ); document.write( ":
\n" ); document.write( "Find the speed required to cover 45 ft in 3 sec, add that to 45 mph
\n" ); document.write( ":
\n" ); document.write( "45/3 = 15 ft/sec
\n" ); document.write( "How fast is that in mph
\n" ); document.write( "\"%283600%2A15%29%2F5280\" = 10.227 mph faster than the truck
\n" ); document.write( "therefore
\n" ); document.write( "45 + 10.227 = 55.227 mph, the speed of the car \n" ); document.write( "
\n" );
