document.write( "First half of the distance is 5 km.\r\n" );
document.write( "Second half of the distance is 5 km, too.\r\n" );
document.write( "\r\n" );
document.write( "For the first half of the distance she spent  = 1 hour.\r\n" );
document.write( "Hence, for the second part of the distance she spent 1 hour 40 minutes - 1 hour = 40 minutes.\r\n" );
document.write( "\r\n" );
document.write( "Thus at the second part Debbie covered  5 km in 40 minutes =  hour.\r\n" );
document.write( "Then she traveled the second half at the speed of  =  = 7.5 .\r\n" );
document.write( "\r\n" );
document.write( "Answer.  7.5 .\r\n" );
