Question 5: Fast figures
If 42 (rounded up to a full whole number) is 7299 (or maybe 7180) and 1.6 is 223 (again rounded up), what is 0.1?
Clues given during the week were: More about sports than a maths question... Time and distance... Record breakers... Go the extra mile...
Answer: A very tricky question, made even more difficult by a blip with 1.6 being incorrectly keyed in as 1.5 – apologies for the error. Despite the hurdles, a select band of readers made it to the finishing line: correctly working out the answer as 10 (9.58s) by identifying that these were the official world record times in seconds for the men’s marathon, mile and 100 metres. Extra well done, so, to: Michele Girardi, Scame Mastaf Spa, Suisio, Italy; Andrew Knox, Rubbond International, Ohé en Laak, The Netherlands; France Veillette, chef environnement, Usine de Joliette, Bridgestone Canada Inc., Canada: Jose Padron, material development specialist, Waterville TG Inc., Waterville, Québec, Canada; Stephan Paischer, head of product management special products, Semperit AG Holding, Vienna, Austria; Yuichi (Joe) Sano, Sumitomo Electric Industries Ltd, Itami, Japan; John Bowen, consultant, Bromsgrove, UK; David Mann, polymer business development / language coach, Arras, France.
