- A policeman spots a thief from 480 meters away.

- Both start running, with the thief at 19 km/h and the policeman at 23 km/h.

- The speed difference is 23 km/h - 19 km/h = 4 km/h.

- Convert this speed difference to meters per second: 4 km/h = (4000/3600) m/s = 10/9 m/s.

- The initial distance between them is 480 meters.

- Time to catch up: $Time = \frac{480 m}{10 / 9 m/s} = 432 seconds$ .

- In this time, the thief runs $432 seconds \times \frac{19 \times 1000}{3600} m/s = 2280 meters$ .

Option 2: 2280 m
