Should've not spend as much time as I did on this problem, naming the parameter 'arr' confused me.

Don't do drugs kids.

Reg is too OP, nice work

Once again, the task condition: "if true, you can half the swimming speed of the shark"
A simple example: a shark will swim 6 km at a speed of 6 km/h in 1 hour, at a speed of 3 km/h - in 2 hours...

I think the instructions should give the variables in the same order as listed in the function.

You code is still incorrect. You need to debug your solution. If you don't know where to start, you may find some helpful tips there: https://docs.codewars.com/training/troubleshooting/

I have tried using "return" instead of "console.log" I still happend to recieved "undefined", would it be something else in my code?

You're a bit faster than the shark (3m/s vs 2m/s), but you're also much further away from the pontoon than it is (31m away vs. 13m away), which means it will get to the pontoon first and you will be eaten if you try to get past it.

My brain hurts now.
