A 240-meter long train crosses a pole in a platform in 8 seconds . Determine the speed of the train in km/hr.

A 240-meter long train crosses a pole in a platform in 8 seconds . Determine the speed of the train in km/hr. Correct Answer 120

Velocity = Distance / time = 240 m / 8 sec = 30 m/s Now, 1 m/s = 1/1000 km/s = (1/1000) x 60 x 60 km/h = 3.6 km/h So,  30 m/s = 30 x 3.6 km/h =  108 km/h

In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: A 300 m long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform? Quantity B: A train running at 60 kmph crosses a pole in 30 seconds. What is the length of the train?
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?
To cross a man standing on platform, a train takes 40 seconds. When the same train crosses the platform at half its speed, it crosses the platform in 120 seconds. Find the ratio of lengths of train and platform.
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).
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?
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.
