My logic is not working . Someone pls help me out . Here the question is :

On the M53 is a sign Warington 20. Just over half a mile further on is another sign ‘Warrington 19’. This is not surprising, since the distance are rounded to the nearest while 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 must now be btwen ?

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
