It takes a local train 30 minutes longer than the express to travel 216km.The local averages 6km/h less than the express.What is a possible equation which could be used to determine the speed of each train?
\n" ); document.write( "I said 216/x-6 - 216/x = 30 but I was marked wrong :(
\n" ); document.write( ":
\n" ); document.write( "You have to convert 30 min to hrs
\n" ); document.write( " $\"216%2F%28%28x-6%29%29\"$ + $\"216%2Fx\"$ = $\"1%2F2\"$
\n" ); document.write( ":
\n" ); document.write( "If you solve this you will get speeds of 48 and 54 km/hr
\n" ); document.write( ":
