Perplexity 1: cake walk Mystery Cache

This is a puzzle cache. The container is not hidden at the coordinates given. You can find the correct coordinates by using the information on this page to solve the puzzle!

This cache is part of a series around the area where I live. I hope that you enjoy them and that they are sufficiently challenging without being too frustrating...

NB: the cache is OUTSIDE the newly fenced off area. You do NOT have to cross the fence

Three cachers each set out from different locations and began walking at the same fixed speed straight towards the cache. As each one walked he or she munched on a slice of their favourite cake.

• Rachel starts from N51 44.632 W00 22.073 and it took her 25 seconds to finish her cake (it was only a small piece).
• Trevor starts from N51 44.636 W00 22.153 and it took him 61 seconds to finish his cake.
• Ashley starts from N51 44.686 W00 22.173 and he managed to make his cake last 89 seconds.

At the very moment each cacher finished their cake, they looked up and realised that they had all arrived at the cache at the very same instant. So they quickly signed the log and headed off together. To get some more cake.

Note: for the purposes of the puzzle pretend that degrees of latitude and degrees of longitude are the same size as each other on the ground (even though they aren't)
