Answer:

pls mark me as brainliast!!!!

Step-by-step explanation:

t is not more than 20cm

t is atleast 15cm

therefore;

because, for every step there is varying distance at xy

the gaps are of the range 15 to 20,therefore to get the number of step along xy distance;

x y/15 + x y/16 + xy/17 +xy/18 +xy/19 + xy/20=total number of steps
