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 26m behind the tourist and running at 6.0m/s. the tourist reaches the car safely what is the maximum possible value for d?
i got the answer, but the unit just doesnt match.
my way to do it is:
who can give me some hints?
thanks a lot!!!
bear distance= 26 +tourist distance
6*time=26 + 4*time solve for time.
time= 13 seconds
6*time= bear distance
