Let 35min = the duration of the car traveled
\n" ); document.write( " 69kph = the speed of the car
\n" ); document.write( "A car reached raipur from ranchi in 35 minutes with an average speed of 69km/hour.
\n" ); document.write( "Distance = (rate)(time)
\n" ); document.write( " d = (69)(35)
\n" ); document.write( " d = 2415/60
\n" ); document.write( " d = 40.25
\n" ); document.write( "
\n" ); document.write( "If average speed is increased by 36 km/hr
\n" ); document.write( " 40.25 = (69+36)t
\n" ); document.write( " 40.25 = 105t
\n" ); document.write( "(.38)(60)= t
\n" ); document.write( " 23 = t\r
\n" ); document.write( "\n" ); document.write( "The it took to reach raipur with a speed of 105kph is 23 minutes.
\n" ); document.write( "
\n" ); document.write( "
