Question by question

A question scores 100 minus the bracket’s width as a percentage of the track, if the answer is inside it, and nothing if it is outside. The tenth-of-the-track bracket below is the one a confident player was aiming for.

  1. How many digits does a googol have? 101 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 80 to 130 is a tenth of the track and scores 90; the whole track scores 0.
  2. How fast does the International Space Station orbit? 17,500 miles per hour — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 14,000 to 22,000 is a tenth of the track and scores 90; the whole track scores 0.
  3. How high is an Olympic diving platform? 33 feet — in the lower third of its track. A bracket from 28.5 to 37.5 is a tenth of the track and scores 90; the whole track scores 0.
  4. How many minutes are in 29 days? 41,760 — in the upper third of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 33,000 to 53,000 is a tenth of the track and scores 90; the whole track scores 0.
  5. What year was the first text message sent? 1,992 — near the middle of its track. A bracket from 1,988 to 1,996 is a tenth of the track and scores 90; the whole track scores 0.
