Trains A and B are traveling in the same direction on parallel tracks.
\n" ); document.write( " Train A is traveling at 80 mph and train B is traveling at 100mph.
\n" ); document.write( " Train A passes a station at 2:20 PM.
\n" ); document.write( " If train B passes the same station at 2:32 PM, at what time will train B catch up to train A?
\n" ); document.write( ":
\n" ); document.write( "From the given information, we know that Train B is 12 min behind A at at 2:20 pm
\n" ); document.write( "therefore Train B is:
\n" ); document.write( "\"12%2F60\" * 100 = 20 miles behind Train A at that time.
\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 dist = Train A dist + 20 mi
\n" ); document.write( "100t = 80t + 20
\n" ); document.write( "10t - 80t = 20
\n" ); document.write( "20t = 20
\n" ); document.write( "t = 1 hr for B to catch A
\n" ); document.write( ":
\n" ); document.write( "Find the time from 2:20 pm:
\n" ); document.write( "2;20 + 1:00 = 3:20 pm, Train B catches Train A \n" ); document.write( "
\n" );
