Algebra.Com's Answer #276926 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 60 miles per hour and train B is traveling at 80 miles per hour. Train A passes a station at 3:25 am. If train B passes the same station at 3:40 am, at what time will train B catch up with train A? \n" ); document.write( "... \n" ); document.write( "Train A speed 60 mph \n" ); document.write( "train B 80 mph. \n" ); document.write( "Train A passes a station at 3:25 am. \n" ); document.write( "If train B passes the same station at 3:40 am, \n" ); document.write( ".. \n" ); document.write( "Speed train B - speed train A = catch up speed \n" ); document.write( "80-60 = 20 mph. \n" ); document.write( ".. \n" ); document.write( "time between trains passing the station 3.40 -3.25=15 minutes = 1/4 hour \n" ); document.write( ".. \n" ); document.write( "in 1/4 hour train A travesl 60*1/4 = 15 miles. \n" ); document.write( "... \n" ); document.write( "catch up time = catch up distance / catch up speed \n" ); document.write( "catch up time = 15/20= 3/4 hours \n" ); document.write( ".. \n" ); document.write( "Train B will catch up with Train A at 3.40 + 0.45= 4.25 pm \n" ); document.write( ".. \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
