A thief running at 7 km/h is chased by a policeman whose speed is 12 km/h. If the thief is 280 m ahead of the policeman, then the time required for the policeman to catch the thief will be:
1
\(3 \frac{1}{25}\) minutes
2
\(3 \frac{9}{25}\) minutes
3
\(4 \frac{9}{25}\) minutes
4
\(3 \frac{2}{25}\) minutes
