- A train moves with a speed of 108 Km/h
- A speed of 14 meters per second is the same as?
- A train 150 meter long passes a km stone in 15 seconds
- A train of length of 150 meters takes 40.5 seconds to cross
- A train 132 meter long passes a telegraph pole in 6 seconds
- A train 108 meter long moving at a speed of 50 km/h crosses another train which is coming from opposite direction.
As, both trains are moving in opposite direction so their average speed will be determined by adding.
Taking the total distance 108 + 112 = 220 meter, the speed of other train can be find out easily.
Speed = Distance/Time
Speed = ?
Given speed = 50 km/h
Now, in m/sec
Given speed = (50 x 1000)/3600 = 125/9 m/sec
Let the required speed = y
Relative speed = 125/9 + y
Total length = 108 + 112 = 220 meter
Speed = distance/time
125/9 + y = 220/6
y = 220/6 – 125/9
y = (660 – 250)/18
y = 410/18
y = 205/9 m/sec
y = 22.778 m/sec
And in km/h
y = (22.778 x 3600)/1000
y = 82 km/h answer
A train 108 meter long moving at a speed of 50 km/h crosses a train 112 meter long coming from opposite direction in 6 seconds. The speed of the second train will be 82 km/h.
