Super Challenge/Kua takoto te Manuka

Question - Tuesday

Each day, Monday to Thursday there will be one tricky question for you to answer.  The answer will be a number.

Students will need to record their daily answers.

On Friday, students can submit their Super Challenge daily answers, and the total of the daily answers, and submit them online.

If this total is correct, they will get a link to a page where they can fill in their name and school. Students can then print out their Maths Week Super Challenge

Certificate. The student’s school will also get a notification of their success.

If the total is incorrect, a message comes up to tell the student. The student can then go back, change an answer, and re-submit it. If the total is then correct, the student will get the Maths Week Super Challenge Certificate.

The answers to the Super Challenge questions will be available to teachers after the end of Maths Week.

Tuesday

The first person to run a mile in less than four minutes was Roger Bannister of England, who did so on 6 May 1954.  The current record for a mile is 3 minutes 43.13 seconds, and was set by Hicham El Guerrouj of Morocco, at age 24, on 7 July 1999.

Even though athletics mainly uses metric units for distances (metres and kilometres) for events these days, being able to run a mile in 4 minutes or less was a long-held ambition of middle distance runners for many years, and is still a standard for professional middle distance runners in several cultures.

Taking 1 mile as 1.60934 km, at what average speed was Hicham El Guerrouj running in kilometres per hour, to the nearest kilometre per hour? 

Do not include the units when you submit your answer.
