Correct Answer - Option 2 : 500 m

**Given:**

Speed is 60 km per hour,

Train passed through a 1.5 km long tunnel in two minutes

**Formula used:**

Distance = Speed × Time

**Calculation:**

Let the length of the train be L

According to the question,

Total distance = 1500 m + L

Speed = 60(5/18)

⇒ 50/3 m/sec

Time = 2 × 60 = 120 sec

⇒ 1500 + L = (50/3)× 120

⇒ L = 2000 - 1500

⇒ L = 500 m

**∴ The length of the train is 500 m.**
