in going a certain distance, a train travelling at the rate of 40 km/h takes 2 hours less than a train travelling at 30 km/h. Find the distance.
\n" ); document.write( "-----
\n" ); document.write( "1st train::
\n" ); document.write( "rate = 40 km/h ; time = x-2 hrs ; distance = r*t = 40x-80 km
\n" ); document.write( "--------
\n" ); document.write( "2nd train:
\n" ); document.write( "rate + 30 km/h ; time = x hrs ; distance = r*t = 30x km
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "dist = dist
\n" ); document.write( "30x = 40x - 80
\n" ); document.write( "-10x = -80
\n" ); document.write( "x = 8 hrs
\n" ); document.write( "---
\n" ); document.write( "Ans: Distance = 30x = 30*8 = 240 km
