Algebra.Com's Answer #39746 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! A jogger runs into the country side at a rate of 10 mph. He returns along the same route at 6 mph. If the total trip took 1 hour 36 minutes, how far did he jog? \n" ); document.write( ": \n" ); document.write( "Let d = distance one way: Change 36 min to hrs: 36/60 = .6 hrs \n" ); document.write( "Time = dist/speed \n" ); document.write( ": \n" ); document.write( "Write a time equation, find d: \n" ); document.write( "Time out + time back = 1.6 hrs \n" ); document.write( " d/10 + d/6 = 1.6 \n" ); document.write( ": \n" ); document.write( "Get rid of the denominator, mult eq by 30, resulting in: \n" ); document.write( "3d + 5d = 1.6(30) \n" ); document.write( "8d = 48 \n" ); document.write( "d = 48/8 \n" ); document.write( "d = 6 mi one way. Total he jogged = 12 mi \n" ); document.write( ": \n" ); document.write( "Check: 6/10 + 6/6 = 1.6 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
