TIME AND DISTANCE

TIME AND DISTANCE

  1. If a train crosses a pole means it crosses it’s own length.
  2. If a train crosses a bridge means it crosses (it’s own length + length of the bridge)
  3. When a train is passing another train completely (whether moving in the same direction or in opposite directions), it has to cover a distance equal to the sum of the lengths of the two trains.
  4. If two moving trains (in the same direction) crosses each other then relative speed = (speed of the faster trains—speed of the slower train)
  5. If two trains are moving in the opposite directions then the relative speed = (speed of the Ist train + Speed of the 2nd train)
  6. If without stoppage a train covers a distance at an average speed of x1km/hr and with stoppage it covers a distance at an average speed of x2 km/hr then it’s

Some Important points based on Trains

  1. When two trains are moving in opposite directions their speeds should be added to find the relative speed.
  2. When they are moving in the same direction the relative speed is the difference of their speeds.

  1. When a train passes a platform it should travel the length equal to the sum of the lengths of train & platform both.
