Calculating distance road
I struggle for a long while with solving this problem, but can't seem to find a solution. I'm not really a mathematical genius.
On asks to calculate the quickest route from A to B (by foot).
There are 2 ways to get there:
1. From A to X at 5 km/h and then from X to B at 2 km/h -> this route takes 16 minutes 59 seconds
2. From A to Y at 5 km/h and then from Y to B at 2 km/h -> this route takes 19 minutes 25 seconds
The aim is to find out what the distance is
From A -> X and X -> B
From A -> Y and Y -> B
There are a few catches .
- The angle between A-> X and A-> Y is 95°, but I do not know whether this is important.
- The angles between A-> X and X-> B and also A-> Y and Y-> B are not necessarily 90 °
Thus Pythagoras is in my eyes not suitable for solving this problem.
How should I deal with this problem? Preferably as understandable as possible please.
