Speed of a Jogger in Ealing
We see many healthy joggers in Ealing, and today, we wondered at how fast they were running. My friend was telling me she ran 3.85 miles in 34 minutes. Then I thought that the average speed would be A.BCDE miles per hour (to the nearest 4 decimal places), and I made the comment she would be able to make around A miles in one hour. She then shook her head and suggested that could only be true if we assumed she could keep up the same pace for the whole hour, which would be unlikely.
This led me thinking. Perhaps we should use another timescale to measure speed – one that would be much shorter, so we could discuss paces at different moments during the run. Physicists have been using metres per second as their standard speed measurement units. So I told her that this would be F.GHIJ metres per second. We thought this was a measurement that was much easier to appreciate.
The published location is the beginning and the end of a famous annual half-marathon event at Ealing, and the cache is not there. Instead it is at: N51 30.HFA, W000 18.(A+J)G(C-I). You will need a pen and may need tweezers.
Optional: Do you ever visit a trail of geocaches? How fast do you reckon you walk on such a trail? You may wish to tell us your pace on your find logs.
