| Algebra.Com's Answer #287123 by graphmatics(170)     You can put this solution on YOUR website! Let x be the amount of time at 38KM/Hr and y be the amount of time at 28KM/hr then \n" ); document.write( "x + y = 5 and \n" ); document.write( "38*x + 28*y = 160 \n" ); document.write( "So we solve this system of equations \n" ); document.write( " 
 \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the amount of time he traveled at 38KM/hr is 2, hence the distance traveled is 2hr*38KM/hr or 76KM \n" ); document.write( "At 38KM/hr we get \n" ); document.write( "3hr*28KM/hr or 84KM \n" ); document.write( " \n" ); document.write( " |
