Rankle #85 answer: average annual discharge (lowest to highest)

The answer

Rank by average annual discharge (lowest to highest)

1. 1River Thames66 cubic metres/second
2. 2River Nile2,830 cubic metres/second
3. 3Mississippi River16,790 cubic metres/second
4. 4Amazon River209,000 cubic metres/second

Why this order

Ranked lowest to highest, River Thames (66 cubic metres/second) goes at the top and Amazon River (209,000 cubic metres/second) at the bottom.

The closest call is River Nile (2,830 cubic metres/second) against Mississippi River (16,790 cubic metres/second), about 5.9 times apart. That is the swap most likely to cost a point.

The biggest gap is between River Thames and River Nile, about 43 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 3,200.

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

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