\n" ); document.write( "Time = Distance / speed
\n" ); document.write( "time taken by me = 50km
\n" ); document.write( "speed = 83 km/h
\n" ); document.write( "time = 50/83 hours = 0.60 hours
\n" ); document.write( "..
\n" ); document.write( "Friend 's speed = 92km/h
\n" ); document.write( "time = 50 /92
\n" ); document.write( "= 0.54 hours.
\n" ); document.write( "Time he has to wait = 0.6 - 0.54
\n" ); document.write( "=0.06 hours
\n" ); document.write( "= 0.06 * 60 = 3.6 minutes
\n" ); document.write( "
\n" );
