at the same moment, two trains leave Edinburgh and London.They move towards each other with constant speeds. the train from Edinburgh is moving at a speed of 60 miles per hou, and the train from London is moving at a speed of 40 miles per hour. The distance between the two places is 350 miles. how long after their departure wil they meet?
\n" ); document.write( "E to L DATA:
\n" ); document.write( "distance = x miles ; rate = 60 mph ; time = x/60 hrs
\n" ); document.write( "----
\n" ); document.write( "L to E DATA:
\n" ); document.write( "distance = 350-x miles ; rate = 40 mph ; time = (350-x)/40 hrs
\n" ); document.write( "-------
\n" ); document.write( "Equation::
\n" ); document.write( "time = time
\n" ); document.write( "x/60 = (350-x)/40
\n" ); document.write( "------
\n" ); document.write( "40x = 60*350 - 60x
\n" ); document.write( "100x = 60*350
\n" ); document.write( "x = 60*3.5 = 210 miles
\n" ); document.write( "----
\n" ); document.write( "Ans: time = x/60 = 210/60 = 21/6 = 7/2 = 3.5 hrs
