A train crosses a stationary pole in 20 seconds and a bridge in 32 seconds. If the length of the bridge is 1200 metres, then what
is the speed of the train?
360 km/h
180 km/h
270 km/h
450 km/h
- The train takes 20 seconds to pass a stationary pole. This time indicates how long it takes the train to cover its own length.
- The train crosses a 1200-meter bridge in 32 seconds.
- Time to cross the bridge includes the time to cover its own length and the bridge's length.
- Calculate speed using the difference in time for the pole and the bridge:
Bridge Time - Pole Time=32−20=12 seconds
- The train covers 1200 meters in these 12 seconds.
- Speed of the train: 1200meters12seconds=100m/s.
- Convert meters per second to kilometers per hour: 100×3.6=360km/h.
The correct option is: Option 1: 360 km/h
