If you are looking for an exact number it would be 1,736.17 but a rounded number would be 1,736. Reason for this is do 816/47=17.3617 then multiply by 100 to get 1,736.17.
you would get this by doing 100/47 which you would then multiply that number by the distance traveled so far which is 816 and then you would get the total distance.
