A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 3.55 m/s. The car is a distance d away. The bear is 17.1 m behind the tourist and running at 4.84 m/s. The tourist reaches the car safely. What is the maximum possible value for d?

Answer 1

Both traveled same time .

d/3.55=T
(d+17.1)/4.84=T

set them equal, solve for T.
Now, use the first equation to solve for d.
