Algebra.Com's Answer #120176 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 the parallel tracks. train A is traveling 80 miles per hour and train B is traveling at 90 miles per hour. Train A passed a station at 1:20am if train B passes the same station at 1:32am At what time will train B catch up with train A? \n" ); document.write( ": \n" ); document.write( "An easy to do this is use the relative speed between the trains which is: \n" ); document.write( "90 - 80 = 10 mph \n" ); document.write( ": \n" ); document.write( "At 1:20 Train B is 12 min behind A \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( "At the relative speed of 10 mph, how long will it take to cover 18 mi? \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( "1:20 + 1:48 = 3:02 train b catches train a \n" ); document.write( " \n" ); document.write( " |
