Correct Answer - Option 2 : 82 kmph

**Given:**

The speed of a truck is 1/3rd the speed of a train.

The train covers 1230 kms in 5 hours.

**Formula used:**

Speed = Distance/Time

**Calculation:**

The train covers 1230 kms in 5 hours.

Speed of the train = Distance/Time

⇒ 1230/5

⇒ 246 km/hr

According to the question,

Speed of truck = 1/3rd the speed of a train

⇒ Speed of truck = (1/3)× 246 km/hr

⇒ 82 km/hr

**∴ Speed of the truck is 82 km/hr.**
