Hi!

First I want to ask if the example is OK in this task?
That is, I think numbers are correct, but it is possible to collide with others not only at the last possible moment.
For egzample you start at x=-25 and end at x=15, then going with speed 2sqrt(5) <5
you will collide with the first one at time=2,5 and with the second at time =7,5.
There is of course infinitely many other possibilities.
Example would be also OK if you decreased speed limit from 5 to 2.

Another question is if it is possible to end up at equal point with angles different from 0 and +-45 degrees?

Best regards
Adam

Hi,

The comment after the example was indeed misleading, I've fixed it according to your suggestion.

This question is left to you to answer smile.

I have question for "You can decide at which point along the side of the street you will wait for the green light (any real coordinate other than a place where some other pedestrian is already standing) and at what angle and at what speed you intend to cross"
I understand, I can start walking from any real coordinate other then others pedestrains, but what about my speed and angle? Should I limit my speed only to integer value from 1 to 10000, and my angle only to integer values from -5000 to 5000? Or I have full freedom regarding this two parameters?
