On the M53 is a sign 'Warrington 20'. Just over half a mile further on is another sign 'Warrington 19'. This is not really surprising, since the distances are rounded to the nearest whole number of miles e.g. numbers of 4.5 and over but less than 5 become 5, numbers of 4 and over but less than 4.5 become 4. Half a mile further along the road is a sign showing 'Warrington 18'. The distance to Warrington must now be between
A.
17.5 miles and 17.6 miles
B.
17.6 miles and 18.0 miles
C.
18.0 miles and 18.2 miles
D.
18.2 miles and 18.4 miles
E.
18.4 miles and 18.5 miles
