At 9:00 A.M. Paul starts driving from Alphaville to Betaburg at 40 km/hour. Sometime later, Nabil leaves Betaburg and drives at 60 km/hour. They meet at the half-way point between the cities at 1:00 P.M. At what time did Nabil start driving?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Paul travels 4 hours to meet nabil . So he travels 40* 4 = 160 kms.\r
\n" ); document.write( "\n" ); document.write( "this is the mid point. so total distance between cities = 320 kms\r
\n" ); document.write( "\n" ); document.write( "when Paul drives at 40 km/hr paul takes 4 hours\r
\n" ); document.write( "\n" ); document.write( "when Nabil goes at 60 kms/hr he will take 40/60 * 4 = 8/3 hours\r
\n" ); document.write( "\n" ); document.write( "= 2 hours 40 mins\r
\n" ); document.write( "\n" ); document.write( "1 hour 20 mins less than Paul\r
\n" ); document.write( "\n" ); document.write( "So he leaves at 10.20\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
