Algebra.Com's Answer #139955 by uday1435(57)![]() ![]() You can put this solution on YOUR website! Since the police car has a 3hr headstart, and is moving at 40 mph, he is 3 x 40 = 120 miles ahead of the motorcycle. To catch up this gap he has a relative speed of (60-40 = 20mph). \n" ); document.write( "So the time needed to catch up = distance/speed = 120/20 = 6 hours. \n" ); document.write( "In that time he has to travel a distance = speed x time = 60 x 6 = 360 miles\r \n" ); document.write( "\n" ); document.write( "Amswer: 360 miles\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you still need further clarifications please contact udayakumar.t.r@gmail.com \n" ); document.write( " |
