Algebra.Com's Answer #335800 by lwsshak3(11628) ![]() You can put this solution on YOUR website! Trains A & B are traveling in the same direction on parallel tracks. Train A is traveling at 40 miles per hour and train B is traveling at 48 miles per hour. Train A passes the station at 12:20 A.M. If train B passes the station at 12:35 A.M., at what time will train B catch up to train A? \n" ); document.write( "** \n" ); document.write( "let x=travel time of train A in hrs \n" ); document.write( "(x-15/60)=(x-1/4)=travel time of train B in hrs \n" ); document.write( "Both trains must travel the same distance \n" ); document.write( "Distance=speed*travel time \n" ); document.write( "40x=48*(x-1/4)=48x-12 \n" ); document.write( "8x=12 \n" ); document.write( "x=1.5 hr \n" ); document.write( "Ans: \n" ); document.write( "Train B will catch up to train A in 1.5 hrs at 1:50 A.M. \n" ); document.write( " |
