Train A is traveling at 80 mph and train B is traveling at 88 mph. Train A passes the train station at 9:25. Train B passes the same station at 9:55. What time will it be when train B catches up with train A? \n" ); document.write( "------------------ \n" ); document.write( "Train A DATA: \n" ); document.write( "rate = 80 mph; time = x hrs ; distance = 80x miles \n" ); document.write( "-------------------------------- \n" ); document.write( "Train B DATA: \n" ); document.write( "rate = 88 mph; time = (x-(1/12)) hr. ; distance = 88(x-(1/12)) miles \n" ); document.write( "------------------------------ \n" ); document.write( "EQUATION: \n" ); document.write( "distance = distance \n" ); document.write( "80x = 88(x-(1/12)) \n" ); document.write( "80x = 88x - (22/3) \n" ); document.write( "8x = 22/3 \n" ); document.write( "x = 11/12 hr \n" ); document.write( "x = 55 minutes \n" ); document.write( "Ans: 9:25 + 55 minutes = 10:20 \n" ); document.write( "==================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
