Maths 4/8/2020 Estimating distances

Today in maths I did an estimation task of where I had to estimate a certain distance of using every second foot step for a certain amount of paces and when we got to our designated distance we added them up using our key and I had 70 steps for 1 hundred metres  and out of 500 meters it was 350 second steps and so on.This was to help measuring our distances with out any calculator or devices and increasing our estimating distancing.
