Rankle #61 answer: resting heart rate (slowest to fastest)

The answer

Rank by resting heart rate (slowest to fastest)

1. 1Blue whale~8 bpm
2. 2Human~70 bpm
3. 3Cat~150 bpm
4. 4Mouse~600 bpm

Why this order

Ranked slowest to fastest, Blue whale (~8 bpm) goes at the top and Mouse (~600 bpm) at the bottom.

The closest call is Human (~70 bpm) against Cat (~150 bpm), about 2.1 times apart. That is the swap most likely to cost a point.

The biggest gap is between Blue whale and Human, about 8.8 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 75.

These are the figures the game reveals after you submit. They are rounded and the ones marked ~ are typical or estimated values; only the order is scored.

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