Rankle #37 answer: aircraft maximum speed (slowest to fastest)

The answer

Rank by aircraft maximum speed (slowest to fastest)

1. 1Cessna 172296 km/h
2. 2Boeing 747908 km/h
3. 3Concorde (cruise)2,179 km/h
4. 4X-43A hypersonic11,385 km/h

Why this order

Ranked slowest to fastest, Cessna 172 (296 km/h) goes at the top and X-43A hypersonic (11,385 km/h) at the bottom.

The closest call is Boeing 747 (908 km/h) against Concorde (cruise) (2,179 km/h), about 2.4 times apart. That is the swap most likely to cost a point.

The biggest gap is between Concorde (cruise) and X-43A hypersonic, about 5.2 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 38.

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.
