document.write( "Bob is traveling home at a constant speed. After one-half hour, he is 77.5 miles from home and after one hour, he is 55 miles from home. Write a linear equation that gives the distance from home,y (in miles), in terms of the time x (in hours). How long will it take Bob to get home?<BR>\n" );
