Question 1205270


 the distance between ({{{-1}}},{{{-4}}}) and  ({{{3}}},{{{-5}}}) on the map is

{{{d=sqrt(3-(-1))^2 +((-5-(-4))^2)=sqrt((3+1)^2 +(-5+4)^2)=sqrt(16+1)=sqrt(17)=4.12311}}}

with each unit on the grid representing {{{0.5km}}}, the direct distance will be

{{{d=4.12311*0.5km}}}

{{{d=2.06km }}}
