A 100 metre long train crosses a pole in 8 seconds. What is its speed in kilometres per hour?

A 100 metre long train crosses a pole in 8 seconds. What is its speed in kilometres per hour? Correct Answer 45, 45

Given:

Length of the train = 100 m

Time = 8 seconds

Formula used:

Speed = Distance/Time

1 m/s = 18/5 km/hr

Calculation:

Here Distance travelled = Length of the train

∴ Speed = 100/8 m/s

⇒ (100/8) × (18/5) = 45 km/hr

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.
