document.write( "Question 1144165: A family goes on vacation to a water park. During the drive to the water park the weather caused the family to average 44 miles per hours. After their vacation the weather improved, so they could average 80 miles per hour on the return trip. If the distance each way was equal, and the entire time driving was 6.2 hours, find the distance one way to the water park. \n" ); document.write( "

document.write( "\r\n" );
document.write( "Then the time moving  TO        the water park was    hours.\r\n" );

document.write( "\r\n" );
document.write( "The total time was 6.2 hours, which gives you this \"time\" equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     +  = 6.2  hours.\r\n" );
document.write( "\r\n" );
