An eastbound train and a westbound train meet each other on parallel tracks heading in opposite directions. The eastbound train travels 8 miles per hour faster than the westbound train. After 1.5 hours, they are 168 miles apart. At what speeds are the two trains traveling? \n" ); document.write( "--------------------- \n" ); document.write( "Eastbound train DATA: \n" ); document.write( "time = 1.5 hrs ; rate = x+8 mph ; distance = r*t = 1.5(x+8) = 1.5x + 12 miles \n" ); document.write( "--------------------- \n" ); document.write( "Westbound train DATA: \n" ); document.write( "time = 1.5 hrs ; rate = x mph ; distance= r*t = 1.5x miles \n" ); document.write( "------ \n" ); document.write( "Equation: \n" ); document.write( "distance + distance = 168 miles \n" ); document.write( "1.5x + 12 + 1.5x = 168 \n" ); document.write( "3x = 156 \n" ); document.write( "x = 52 mph (speed of the westbound train) \n" ); document.write( "---- \n" ); document.write( "x + 8 = 60 mph (speed of the eastbound train) \n" ); document.write( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================ \n" ); document.write( " \n" ); document.write( " |
