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
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 direction in 6 seconds. The speed of the second train is
20 m/s
long would it take to go 6600 miles by train?
a train can be a kilometer long. A bridge or road could also be. This question is just too vague.
800 meters
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.
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 direction in 6 seconds. The speed of the second train is
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.
245m
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.
The answer is 72Km/hr
20 m/s
That depends on your speed.
