Algebra.Com's Answer #364600 by ankor@dixie-net.com(22740)![]() ![]() 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 80miles per hour. Train A passes a station @ 12:10am. If train B passes the same station @ 12:22am, 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 12:10 pm \n" ); document.write( "therefore Train B is: \n" ); document.write( " \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 + 16 mi \n" ); document.write( "80t = 60t + 16 \n" ); document.write( "80t - 60t = 16 \n" ); document.write( "20t = 16 \n" ); document.write( "t = \n" ); document.write( "t = .8 hrs for B to catch A \n" ); document.write( ": \n" ); document.write( "Convert .8 hrs to minutes: .8(60) = 48 min \n" ); document.write( ": \n" ); document.write( "Find the time from 12:10 pm: \n" ); document.write( "12:10 + 0:48 = 12:58 pm, Train B catches Train A \n" ); document.write( " |
