1. A 240-meter long train crosses a pole in a platfrom in 8 seconds. Determine the speed of the train in km/hr.
- A. 120
- B. 120
- C. 120
- D. 120
Answer: Option E
Explanation:
Velocity = Distance / time = 240 m / 8 sec = 30 m/s
Now, 1 m/s = 1/1000 km/s = (1/1000) x 60 x 60 km/h = 3.6 km/h
So, 30 m/s = 30 x 3.6 km/h = 108 km/h
