Examples of length and width and height?
An old train engine is 45 feet in Length, 7 feet in width and reaches 15 feet in height.
A 180 meter long train crosses a platform of equal length in 18 seconds what is the speed of the train?
After the nose of the train reaches the platform, it takes some number of seconds for thenose to reach the far end. At that time, the whole train is lined up with the whole platform.Then after that, it takes the same number of seconds again for the caboose to reach the far end,and the train to completely clear the platform.So the total time that there's some overlap between the train and platform is twice the timethe train takes to move the length of the platform, which is also the length of the train.Distance = (speed) x (time)180 meters = (speed) x (9 seconds)speed = (180/9) = 20 meters per second
What customary unit can measure a train?
Metre (for its length). Kilometres per hour (speed) Tonnes (Mass)
Train is135m long average speed 120 kmh 50 seconds it passes through tunnel what is the length of the tunnel?
120 km/h = 120,000m/hr = 33.333 m/s Distance travelled in 50 seconds = 33.333 * 50 = 1666.666 metres Tunnel length = distance travelled - train length - 1666.666 - 135 = 1531.666metres
A train moving at a speed 49 MPH is passed by a train moving at 63 MPH a man in first train noticed that the second train too 4.5 seconds to pass him how long is the second train?
4.5 seconds = (4.5/3,600) = 0.00125 hourIn the man's frame of reference, the faster train is moving past him at 14 miles per hour.1 mile = 5,280 feet1 hour = 3,600 seconds14 mph = (14 x 5,280 / 3,600) ft per secondLength = (Speed) x (time) = (14 x 5,280 / 3,600) ft per sec x (4.5) sec = 92.4 ft
