A distance of 33 KM is covered in 1 hr. 12 minutes. If the first 15 KM is covered at the speed of 25 KM per hour. Find the speed during the remaining distance.
\n" ); document.write( "***l
\n" ); document.write( "let x=travel time for first 15 km
\n" ); document.write( "travel time=distance/speed
\n" ); document.write( "x=15 km/25 km/hr
\n" ); document.write( "x=(15/25)=(3/5)hr=36 min
\n" ); document.write( "..
\n" ); document.write( "1 hr 12 min=72 min
\n" ); document.write( "72-36=36=travel time of remaining distance
\n" ); document.write( "remaining distance=33-15=18 km
\n" ); document.write( "speed=18/(36/60)=30
\n" ); document.write( "speed during the remaining distance=30 mph
\n" ); document.write( "
\n" );
