So the units will work, you have to get the ratio
into a form like:
( inches ) / ( sec ) = ( inches ) / ( sec )
------------------
Convert +28+ ft to inches
( ft )x( in / ft ) = in
+28%2A%28+12+%2F+1+%29+=+336+ in
-------------------------
Convert +18+ min to sec
( min )x( sec / min ) = sec
+18%2A%28+60%2F1+%29+=+1080+ sec
-------------------------
Now I can say
+336+%2F+1080+=+x+%2F+216+
+14+%2F+45++=+x+%2F+216+
Multiply both sides by +45%2A216+
+14%2A216+=+45x+
+x+=+3024+%2F+45+
+x+=+67.2+ in
