Rankle #72 answer: length (shortest to longest)

The answer

Rank by length (shortest to longest)

1. 1River Thames346 km
2. 2River Seine777 km
3. 3River Rhine1,233 km
4. 4River Nile6,650 km

Why this order

Ranked shortest to longest, River Thames (346 km) goes at the top and River Nile (6,650 km) at the bottom.

The closest call is River Seine (777 km) against River Rhine (1,233 km), about 59% apart. That is the swap most likely to cost a point.

The biggest gap is between River Rhine and River Nile, about 5.4 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 19.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.

Difficulty: medium, judged by how close the tightest pair is.
