Robin Banks is 325 feet from his hideout and running towards it, if he gets there before being caught he gets away. Officer Willie Ketchup is 170 feet behind Robin also running toward Robin's hideout. Robin is running at 8 ft/s and Willie is running at 12 ft/s. This is the outcome for Robin.   

What is Robin gets away?

Willie is gaining on Robin by 4 ft/s.

So to gain 170 feet on Robin will take Willie 42.5 s.

However, Robin will travel 8 x 42.5 = 340 feet in that time, making it 325 feet to his hideout before Willie can catch up!
