\n" ); document.write( "**
\n" ); document.write( "let x=usual travel time to cover the distance
\n" ); document.write( "let s=usual speed to cover the distance
\n" ); document.write( "distance=speed*travel time=sx
\n" ); document.write( "distance/speed=travel time
\n" ); document.write( "sx/(3/4)s=x+10
\n" ); document.write( "4x/3=x+10
\n" ); document.write( "x/3=10
\n" ); document.write( "x=30
\n" ); document.write( "ans:
\n" ); document.write( "usual travel time to cover the distance=30 min \n" ); document.write( "

\n" );
