  • speed=distance/time
  • here distance=length of the train+length of the pole
  • distance=140+0=140
  • time =12min
  • s=140/12=70ms
  • if u want to convert km/h u must multiply with 15/8
  • so speed(s)=70*15/8km/hour

A train 120 metres long passes an electric pole in 12 seconds and another train of same length traveling in opposite direction in 8 seconds what is the speed of the second train?

Completely ignore the first train.The second train passes the pole in 8sec.In this 8 seconds the train drove 120 meters.So the train has a speed of 15meters per second (120/8=15).Answer: 15 (meters / second) = 54 km/h


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

A train approaching a crossing changes speed from 25 meters per second to 10 meters per second in 240 seconds how can the train's acceleration be described?

Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.


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
