document.write( "Michael drove to a friends house at a rate of 40 mph. He returned by the same route at a rate of 45 mph. The driving time for the round trip was 4 hours. What is the distance Michael Traveled?\r\n" );
document.write( "Ans:\r\n" );
document.write( "Let the distance to the friends house be x miles\r\n" );
document.write( "Distance = Speed * time, or time = Distance / speed.\r\n" );
document.write( "So time taken for driving to the friend's house = x/40\r\n" );
document.write( "And time taken for return = x/45\r\n" );
document.write( "Total time = x/40 + x/45\r\n" );
document.write( "Total time is given to be 4 hours. So we get the equation\r\n" );
document.write( " Multipyling by 360 which is the LCM of 40 and 45,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( " miles approximately.\r\n" );
