How do you solve a train problem in math?
If both trains leave the station at the same time, how far apart will they be at the end of two hours? Train A traveled 120 miles, and train B traveled 140 miles. Because they’re traveling in the same direction, you subtract to find the distance between them: 140 – 120 = 20.
When a train crosses a bridge it has to cover a distance which is equal to?
As the train crosses the bridge, the train covers a distance equal to its length plus an additional distance equal to the length of the bridge to cross it. Thus the distance covered by the train to cross the bridge is d=lT+lB. Substituting the values for lT=50m and lB=250m in the above equation we get, d=50+250=300m.
How do you calculate the relative speed of two trains passing each other?
When two bodies move in the same direction then the Relative Speed = Difference of Speeds i.e for a person a sitting in a train moving with a speed of 60 km/hr in the west direction, another train which is going towards the west with a speed of 40 km/hr, will appear to move at a Speed of (60-40) = 20 km/hr.
How is bridge length calculated?
Formula: length of bridge = (speed of train * time taken to cross bridge) – length of train.
What is the speed of the train on parallel lines?
Speed of the train = 35 km/hr. Q 9 – Two train 128 m and 132m long are running towards each other on parallel lines at 42 km/hr and 30 km / hr respectively . In what time will they be clear of each other from the moment they meet?
How do you find the relative speed of a train?
Find the speed of the train. Let the speed of the train be x km/hr. Relative speed = ( x + 5 ) km /hr = 5 ( x+ 5 ) / 18 m/sec. Distance covered in passing the man = 100m. ∴ 100/ 5 ( x+5) / 18 = 9 ⇒ 45 ( x+ 5) = 1800 ⇒ x + 5 = 40 ⇒ x = 35. Speed of the train = 35 km/hr.
How long does it take a train to pass a man?
Q 5 – A train passes a standing man in 3 seconds and a platform 105 m long in 8 seconds. Find the length of the train and its speed? Let the length of the train be x metres and its speed be y km/hr i.e. (5y/18 ) m/sec.
How long does it take a train to travel 500 miles?
Example: If a train can travel 500 miles with an average speed of 50 miles per hour, how long it would take it to complete a 500-mile route? The answer is 500 / 50 = 10 hours. The answer is 500 / 50 = 10 hours.
