Rankle #119 answer: maximum speed of sound (lowest to highest)

The answer

Rank by maximum speed of sound (lowest to highest)

1. 1Air0.343 km/s
2. 2Water1.48 km/s
3. 3Iron5.1 km/s
4. 4Diamond12 km/s

Why this order

Ranked lowest to highest, Air (0.343 km/s) goes at the top and Diamond (12 km/s) at the bottom.

The closest call is Iron (5.1 km/s) against Diamond (12 km/s), about 2.4 times apart. That is the swap most likely to cost a point.

The biggest gap is between Air and Water, about 4.3 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 35.

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.
