A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 4.2 m/s. The car is a distance d away. The bear is 30 m behind the tourist and running at 6.0 m/s. The tourist reaches the car safely. What is the maximum possible value for d?
So the problem ask to calculate the distance of the car from the bear where as the bear is 30m behind the tourist running 6m/s and the bear runs for 4.2m/s. So base on that, the distance is 70 meters. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications
