Because that is how maths work. 1760 x 31 = 54560
440
4
It is: 4*1760 = 7040 yards
There are 1760 yards in one mile. Therefore, 4 and three-sevenths of a mile is equal to 1760 x 4 + (1760 x (3/7)) = 7794 and two sevenths (that is 7794.285714 recurring) yards.
If 1760 represents yards
It is: 1760/440 = 4 times
There are 1760 yards in one mile. Therefore, one quarter of a mile is equal to 1/4 x 1760 = 440 yards.

1760 * 668 = 1,175,680
5280 * 1760 = 9,292,800
1760 * 762 = 1,341,120
