The train travels 150m in 10seconds, Therefore it travels 900m in 1 minute and thus 54000 metres in 1 hour. The train's speed is therefore 54 kph (kilometres per hour)
Average speed = 80 miles per hour.
10:00 is the answer
At 2:45, Train-A has a 1/2-hour lead on Train-B = 1/2 of the speed of Train-A = 5 miles.Train-B overtakes Train-A at the rate of (50 - 40) = 10 miles per hour.It takes Train-B (5/10) = 1/2 hour to make up the deficit.Train-B catches up to Train-A at 3:15 AM.
For this you have to work out the speed speed=distance/time therefore the speed here is 20feet/15seconds = 1.3333333m/s Now you have to work out the distance distance = speed X time the distance traveled in 3 seconds is 1.3333333m/s x 3 = 4 feet
81 km/hr
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
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

The answer is 72Km/hr
you have to train harder
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.
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 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
A Steam Train Passes was created in 1974.
history of the united states
To cover 4000 metres in 125 seconds the train would be travelling at 71.58 miles an hour. This is the speed over the whole measured distance and not from a standing start
