A train covers a distance of 72 km in 40 minutes. Travelling at the same speed, how many metres will the train cover in 6 seconds?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 180.
First, let's calculate the speed of the train in m/s.
⇒ Speed = Distance / Time = 72 km/40 min = (72 × 1000 m) / (40 × 60 s) = 30 m/s
Now, to find the distance covered in 6 seconds:
⇒ Distance = Speed × Time = 30 m/s × 6 s = 180 meters
Therefore, the train will cover 180 meters in 6 seconds.
