A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 6.27 m/s. The car is a distance d away. The bear is 32.1 m behind the tourist and running at 9.06 m/s. The tourist reaches the car safely. What is the maximum possible value for d?

or them to arrive at the same time, we need

d/6.27 = (d+32.1)/9.06

any value of d greater than that will be fatal for the tourist.
