The 3 inches in actual size is 3%2F12=1%2F4 feet.

OnThePage%2FActual=highlight%284%261%2F2%2F%281%2F4%29=x%2F3%261%2F2%29
for the unknown distance x IN FEET.
You can solve for x and convert into inches.

%285%2F2%29%2F%281%2F4%29=x%2F%287%2F2%29
%285%2F2%29%2A4=x%282%2F7%29
10=%282%2F7%29x
5=x%2F7
x=35
