**Given:**

Length of train = 500m

Speed = 36 km/h

Concept used:

To convert a speed from km/h to m/s, we multiply it by 5/18

**Formula used:**

Distance = Speed × Time

**Calculation:**

Let the length of bridge be x meter

Then, the total distance = x + 500

According to the question,

⇒ x + 500 = 10 × 70

⇒ x = 700 - 500 = 200

**∴ The length of bridge is 200 m.**
