How long will a train of 50 m will take to pass over a bridge of 250 m at a speed of 10ms?

30 seconds
When the front of the train is at the start of the bridge, the back is still 50 metres away.
When the back of the train crosses the bridge then the time stops.
So 50 + 250 = 300
300 / 10 = 30

Can A 150 m long train crosses a bridge that is 850 m long in 100 seconds What is the total distance traveled by the train What is the speed of the train?
To totally cross the bridge the train must travel (850m + 150m) 1 km. 1 km in 100 seconds is 10 m/s roughly 20 mph, so the answer is yes, with ease.
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite?
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite direction in 6 seconds. The speed of the second train is
A train 160 m long crosses 160 m long platform in 16 secondsThe speed of the train is?
20 m/s
what objects is a kilometer long?
a train can be a kilometer long. A bridge or road could also be. This question is just too vague.
How long would it take to travel 600 miles by train?
That depends on your speed.
A 200 meters long train running at a speed of 60 kmhr passes a bridge in 1 minute The length of the bridge is?
800 meters

How long did it take for the train to travel at a speed of 25.0km with 15 cars?
Take the distance and divide by the speed of the train. That is how long it took for the train to travel.
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite?
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite direction in 6 seconds. The speed of the second train is
A 130m long train crosses a bridge in 30 seconds at 45 kmph The length of the bridge is?
245m
A train of certain length travelling with a uniform speed of 36kmhr crosses a bridge of 600m in 80 secfind the length of the train?
200m. Here's the work:The speed of the train in meters per second is:(36km/hr)(1000m/km) / (3600s/hr) = 10 m/sIf it takes 80 seconds to cross, then the distance traveled in 80s at 10m/s is:(10m/s)(80s) = 800mNow, imagine this:The front end of the train travels 800 meters from the time it reaches the bridge until the back end is clear of the bridge. This means that the length of the train equals the distance traveled minus the length of the bridge.So:800m - 600m = 200mThe train is 200m long.
A train is a mile long and so is the tunnel so how long until the train is out of the tunnel?
There is no way to answer correctly without knowing where the train is relative to the tunnel and the speed that the train is traveling.
A 180 meter long train running at a certain speed crosses a signal post in 9 seconds.what is the speed of the train?
The answer is 72Km/hr
How long would it take to travel 46 miles by train?
Speed = distance / time, so time = distance / speed. Therefore, to get the answer, divide 46 miles by the speed of the train.
How long would ittake to travel 112.06 miles on train?
That depends on your speed.
A train 160 m long crosses 160 m long platform in 16 secondsThe speed of the train is?
20 m/s
