Answer the following Route Check:
1) - 10). List in order the even numbered Spot Heights that you pass through. Then fill in any remaining route checks with the Kilometre Squares (from the start, in order) of where you join white roads until you have completed 10 route checks.

This was an all or nothing route card. About half of you got the idea and after that it was easy for you.

TC6 (Out) @ 200 030
TC7 (In) @ 1967 9596

The non-metric units were m = miles, nm = nautical miles (6080 feet), f = furlongs (220 yards), feet or fathoms (6 feet), c = chains (22 yards), y = yards, i = inches.

The conversion rates used were 1km = 0.62137m = 0.5396107nm = 4.97096furlongs(fu) = 49.7096c = 1093.6112y = 546.8056(*)fathoms(fa) = 3280.8336feet(ft) = 39370.003i. Depending upon your reference book, your conversion rates might have been slightly different from these. However, you should have still ended up with the with the same kilometre distances when rounded to two decimal places.

The "as the Crow flies" distances were the straight line measurement in kilometres between consecutive junctions.

So here's the conversion to kilometres you should have ended up with:

(*The figure used however was 548.8056! **1.63 The true distance was 1.63, not 1.43 as computed. However, this would have been diagnosed as an obvious error once the distances either side had been discovered.)
