Algebra.Com's Answer #305667 by mananth(16946)![]() ![]() You can put this solution on YOUR website! two motocyles travel toward each other from cities that are about 320km apart at a rate of 95km/hr and 65 km/hr. They started at the same time. In how many hours will they meet?\r \n" ); document.write( "\n" ); document.write( "Add up the speeds \n" ); document.write( "95+65= 160 km/hr \n" ); document.write( "Distance = 320 km \n" ); document.write( "time = 320/160 \n" ); document.write( "=2 hours \n" ); document.write( "______________________________ \n" ); document.write( "2.
