Question 1054618
The "scale' of a map is the shrinking factor
that the actual size things are shrunk down to
The factor for this map is {{{ 1/50 }}} in/mi
-------------------------------------------
In terms of just units:
[ inches on the map ] = [ inches / mile ]x[ real world miles ]
Plug in the given data:
{{{ 4 = ( 1/50 )*d }}}
where {{{ d }}} = the actual distance in miles
Multiply both sides by {{{ 50 }}}
{{{ 200 = d }}}
200 mi is the actual distance
