It is 11:00 am when you leave point A. You stop for a 30 minute lunch break at point B, then you drive the rest of the way to your destination at point C, which is twice the distance you drove from point A to point B. You drive at an average speed of 50 mph for the trip from point A to point B, and you drive an average of 60 mph from point B to point C. If you arrive at point C at 1:43 pm, what is the total distance you drove </SPAN>\n" );
