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.
