MHB Cross-Border Conversions: Miles to Kilometers

AI Thread Summary
The discussion focuses on converting distances between miles and kilometers for two towns, Aville and Btown, which use different measurement systems. The distance between the towns is 150 miles, with the border located 25 miles from Btown, equating to 200 kilometers for Aville residents. An accident occurring 100 kilometers from Aville needs to be converted into miles for Btown's context. The discussion emphasizes establishing a conversion ratio to facilitate these calculations. Understanding these conversions is essential for effective communication between the two towns.

For the purposes of this problem we make the assumption that 5 miles is exactly 8 kilometers.

Two towns, Aville and Btown are situated in different countries and are connected by a road that is 150 miles long. The border is 25 miles from Btown. People of Aville use the metric system of kilometers, meters, etc. while those of Btown adhere to the English system of miles, feet, etc. People in both towns measure all distances relative to their own town. Thus the people of Aville declare that the border is 200 km "down the road" while those in Btown say that it is 25 miles "down the road". ("down the road" means toward the other town.

When an accident happens at a point 100 km down the road from Aville, the Btown newspaper will announce that it happened ? miles down the road.

More generally, x km down the road from Aville means ? miles down the road from Btown. If a rest area is to be built at a location 71 miles from Btown then it will be ? km from Aville.

Set up a ratio of miles to km so that you can find the scaling factor.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
