From the equation, it can be deduced that the length of the marathon race will be 47905yards.
Let the total length of the marathon race = x
It should be noted that 1 mile = 1760 yards.
Since the length of a marathon race is 26 miles 385 yards, the conversion in years will be:
x = (26 × 1760) + 385
x = 47520 + 385
x = 47905
