Correct Answer - Option 2 : 0

**Given:**

Distance between thief and policeman = 200 m

Speed of thief = 11 km/h

Speed of policeman = 12 km/h

**Formula Used:**

Speed = Distance/Time

**Concept Used:**

If two objects are moving in the same direction with speeds S_{1} and S_{2},

Their relative speed is S_{1} – S_{2}

**Calculation: **

Relative speed = 12 – 11 = 1 km/h

Distance travelled in 1 hour = 1 km

Distance travelled in 60 minutes = 1000 m

⇒ Distance traveled in 12 minutes = 1000/60 × 12 = 200 m

∵ 200 – 200 = 0

**∴ The policeman will catch the thief in 12 minutes.**
