Ryan's house is #175# yards from school.

The relation in such cases is of proportionality i.e. number of steps is proportional to distance and hence

#30/12=x/210#

Here distances are in feet and #x# is distance of Ryan's house from school in yards

Hence, #x=210xx30/12=cancel210^105xx(cancel30^5)/(cancel12^(cancel2)#

= #105xx5=525# feet

and dividing by #3# we get #175# yards

Ryan's house is #175# yards from school.
