This is so incredibly much complicated to me than just multiplying or dividing by 1.6.
And also 55 km is 34 miles, not 31. I had to run it through a converter tool just to be sure.
Edit: I reread your comment. The goal was 50 kilometers. Then the math checks out. Sorry!

just multiplying or dividing by 1.6 is about as accurate as my strategy in the other direction - the real value is almost exactly between them.

I guess as long as it works it works. I don’t have to do much of those conversions though. Here in Norway we are metric in almost all of our measurements. Except for some specialist measures like a carton of eggs is a dozen. We often say things happened a fortnight or so ago, etc.
