A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 5.04 m/s. The car is a distance d away. The bear is 17.5 m behind the tourist and running at 7.26 m/s. The tourist reaches the car safely. What is the maximum possible value for d?

Answer 1

time=d/5.04
time=(d+17.5)/7.26

set them equal, solve for d

Answer 2

How do you set them equal to d. I am having a lot of trouble doing this.
