How Far Can a Tourist Run Before a Bear Catches Up?

[ayerski]

Homework Statement

A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 4.0m/s. The car is a distance d away. The bear is 26 m behind the tourist and running at 6.0 m/s. The tourist reaches the car safely. What is the maximum value for d?

Homework Equations

v = d/t

The Attempt at a Solution

I've been trying to use multiple variables to solve but i just can't seem to figure out a strategy.

To solve this question you need to work out how long the bear would take to catch up to the tourist, and then use this time and the tourists speed to figure out the distance between him and the car.

Hope that helps.
