There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
As soon as a passenger train enters the platform, a stray dog starts chasing the train till the end of platform. The train was 200 m long. The platform was 1600 m long. Driver of the train however finds that the dog is not running at all, only pretending to run as neither it moves ahead nor lags behind during the whole time train crosses the platform. But a person standing on the platform tells that the dog was running at a speed of 60 m/s. What was the speed of the train?
A train moving at a speed of 90 kmph crosses a platform in 30seconds. If the time taken by the train to cross the platform when the length of the platform in decreased by 10% is equal to the time taken by the train to cross the platform when the length of the train is decreased by 5%, what is the length of the train (in m)?
A train with uniform speed crosses a 162m long platform in 36 seconds and another platform 120 m long in 30 seconds. Which of the following statements are correct A. As the length of the platform is changing, the time taken to cover the distance will also change.  B. Speed of the train is 7 m/seconds. C. The length of the train is more than the length of platform 1. D. Train is 90 meters long. E. Length of both the platforms to be added to find the length of the train.

Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answer. The length of the first train is 40% more than the length of the second train. Time taken by the first train to cross a 200 m long platform when the second train crosses a person standing on the same platform in 25 sec. If the speed of both trains is 60 km/h and 36 km/h respectively. Quantity A: Numerical value of the time taken by the first train to cross the platform (in seconds) Quantity B: Numerical value of the length of the second train (in Km).

.Magadh express passes a platform during its journey. However a local passenger standing on the platform and was waiting for a local train checks his watch as soon as the train approaches him. When he raises his head, the train had just left him. If the length of the platform was 1800m and the train was running at a speed of 162 kmph, how much time did express take to cross the platform? The man had looked into his watch for 10 sec.
A train has an average speed of 50km/hr over 150 km and it travels at variable speed throughout its journey. The train travels slowest when it crosses a platform with a constant speed. The train is 100m long and the platform is 1250 m long. If the train takes 10minutess to cross the platform, what is the speed of the train during the rest of the journey?
