Question

Mary has walked 8 km, which is 55% of the total distance she will walk. How much farther

does Mary need to walk?

Answer 1

To find the total distance, Divide distance already walked by percentage:

8 / 0.55 = 14.55 km

She already walked 8 so now subtract:

14.55 - 8 = 6.55 km left to walk
