Sorry, I can't quite measure it from here. I guess you'll have to get a ruler and measure it yourself.

line segment to the nearest half inch is measured using the distance formula.

If the line segment is 1 inch shorter than the other line segment in Hopeton, then the length of the line segment would be 1 inch less than the length of the other line segment. So, if the other line segment is x inches long, then this line segment would be x - 1 inches long.

Report the length as x inches to the nearest quarter of an inch.

The distance to a star.
3 inches to the nearest inch and 3 inches to the nearest half inch both refer to a length not less than 2.5 inches and less than 3.5 inches. 3 inches to the nearest quarter inch refers to a length not less than 2.75 inches and less than 3.25 inches.

Yes, of course, you lose more precision if you round to a half inch. Try rounding 0.76 to the nearest half unit, and to the nearest quarter unit, and see what happens.
