the temperature is -5C which is negative so its behind the zero on a number line and 6C is positive which is infront of the zero so it would be 1C by noon
If you add all of the numerators together 3+57+13= 73 Then you would divide that number by 4 73/4= 18.25 So the course would be 18.25 or 18 1/4 miles long.
