Hi @spaceblastxy1428!

It is great that you a trying to analyze and think over the problems that you see!

The Module 4 Day 13 Challenge problem was very well created by Prof. Po and the numbers there are pretty nice

To begin with, if you are changing the angle between the directions where Alice and Bob are came from to the angle that are different from \(90^{\circ}\) (as well as \(180^{\circ}\)) it will be hard to find any tricks or nice answers if the other numbers in problem are not extremely nice and beautiful. So to solve this problem with random numbers will be complicated task.

To solve it you will need to use geometric coordinate system and trigonometry together. You will learn how to do it in more advance classes.
