Detailed Solution
Download Solution PDFGiven:
Length of the train = 150 m.
Time taken to cross the pole = 12 seconds.
Formula Used:
Speed = Distance / Time
To convert m/s to km/h: Speed (km/h) = Speed (m/s) × 18/5
Calculation:
Speed (m/s) = Distance / Time
⇒ Speed = 150 / 12
⇒ Speed = 12.5 m/s
Convert to km/h:
⇒ Speed (km/h) = 12.5 × (18/5)
⇒ Speed = 45 km/h
The speed of the train is 45 km/h.
