This problem makes absolutely no sense to me what-so-ever. I haven't got the faintest idea where to even get started figuring this out. It's probably childs play to most here, but I am really beginng to get extremely stressed.(adsbygoogle = window.adsbygoogle || []).push({});

Here's the problem:

A tourist being chased by an angry bear is running in a straight line toward his car as a speed of 3.9 m/s. The car is distancedaway. The bear is 20 m behind the tourist and running at 6.0 m/s. The tourist reaches the car safely. What is the maximum possible value ford?

So, like I said I don't even know where to begin. I'm not looking for an easy answer here, just a little guidance to start me on my way. It would be greatly appreciated.
