Train A and train B are traveling in the same direction on parallel tracks.
\n" ); document.write( " Train A is traveling 40 mile per hour and train B is traveling 48 miles per hour.
\n" ); document.write( " Train A passes a station at 8:20am if train B passes the same station at 8:35
\n" ); document.write( " at what time will train B catch train A?
\n" ); document.write( ":
\n" ); document.write( "from the given information, we know that train B is 15 min (1/4 hr) behind
\n" ); document.write( " train A, when train A passes the station
\n" ); document.write( ":
\n" ); document.write( "The distance between the trains at this time: \"1%2F4\" * 48 = 12 mi
\n" ); document.write( ":
\n" ); document.write( "Let t = time required for train B to catch train A
\n" ); document.write( ":
\n" ); document.write( "write a distance equation: Dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "Train B travel dist = Train A travel dist + 12 mi
\n" ); document.write( "48t = 40t + 12
\n" ); document.write( "48t - 40t = 12
\n" ); document.write( "8t = 12
\n" ); document.write( "t = \"12%2F8\"
\n" ); document.write( "t = 1.5 hr or 1 hr 30 min
\n" ); document.write( ":
\n" ); document.write( "8:20 AM + 1:30 = 9:50 am, B catches A \n" ); document.write( "
\n" );
