Why, surely it is obvious by inspection that it takes 45/85 of a second (0.53 s). :)

How long does it take to travel that distance”? (For the benefit of American readers, the standard cricket pitch is 22 yards long).

Also when teaching about conversions I've seen questions asking for answers using 'either metric or imperial'. Martin - in the past I've directed you to websites showing such questions and confirmation about being curriculum based.

It does not teach children how to manipulate imperial units. For example, no child in the UK is taught how to solve the problem “Find the average of 3lbs 6oz, 4lbs 2oz, 6lbs 15oz”. They are however taught how to solve the problem “Find the average of 1.53kg, 1.88kg and 3.15kg”. They might even be taught how to use the “Average” button on their calculators.

Shortly after they made imperial part of the curriculum including conversions to and from, usage, etc. In science classes the units were and still are only metric though. From: [email protected] To: [email protected] Subject: [USMA:45745] Mathematics improvement due to metrication Date: Sun, 6 Sep 2009 14:58:23 +1000 Dear All, The Telegraph at http://www.telegraph.co.uk/education/6138456/Maths-standards-no-better-than-mid-70s.html and the Daily Mail at http://www.dailymail.co.uk/news/article-1211345/Maths-skills-standing-thirty-years-GCSE-grades-soaring.html have both reported that metrication has helped students in the UK with decimals knowledge. Here is the quote from The Telegraph: It found secondary pupils were much more familiar with decimals than they were 30 years ago. Researchers put this down to “cultural changes” including metrication and the increased use of calculators and computers.
