Both mile and yard are units of distance thus they are inter convertible.

Distance covered in a marathon is 26.2 miles.

Since, 1 mile=1760 yards

Thus, distance can be converted into yards using the following conversion factor:

[tex]\frac{1760 yards}{1 mile}[/tex]

Thus, distance covered in marathon in yard will be:

[tex]d=26.2 mile(\frac{1760 yards}{1 mile})=46112 yards[/tex]

Therefore, distance of the race is 46112 yards.
