There is a 1km long train.it's passing a 1km bridge with 1km/h. how long takes it??

Question

the train mus pass completely

Answer 1

2 hours

The front of the train will clear the bridge in one hour.

The back of the train (1km behind the front) will just be entering the bridge as the front exits it.

The back will take an additional hour to get across the bridge.

2 hours total time from start to finish

Answer 2

It could be anything between 60 and 120 minutes depending on the angle of the bridge to the train tracks. Remember, it's passing the bridge, not crossing it, so if the bridge runs parallel, it will take an hour for the front of the train to get from the near end of the bridge to the far end, at which point the rear of the train will be equal with the near of the bridge. It will then take another hour for the rear of the train to reach the far end. If the bridge is perpendicular, it'll just take an hour.

Answer 3

if the train starts moving with the speed of 1Km/h at the beginning of the bridge and keeps moving with the same speed ... it will take 2 hours ... one hour to get completely into the bridge , and another hour to go out completely

Answer 4

Well, that depends on the cargo of the train, the mental state of its crew (are they tired?), whether a catastrophic earthquake will strike and destroy the bridge with the train on it, leading to great loss of life and a nasty insurance battle, and the weather.

For example, a train full of cattle might suddenly need to be milked, which makes the train operators groan "Oh, no, not THIS again" and delays them. Then it can take up to six hours. (They're not farm hands; they milk really slowly.)

On the other hand, a train full of coal might just roll on through in two hours.

Or there might be a really strong tailwind, and they get across in 15 minutes, and they're more frightened.

As you can see, we clearly need much more context to answer your query.

Answer 5

2 hours

Answer 6

approximately 3-4 minutes. I even have been working pass united states of america and long distance because of the fact that i became into in grade 4. whilst i became into 15 i became into working 2k in below 8 minutes. bear in techniques that something below 5km is largely a splash. you would be going as rapid as you could.

Answer 8

two days, three hours, fifteen seconds
