Aptitude - Problems on Trains - Discussion

From the question we can predict speed= distance/hour
((by speed=60 km/hr)note the km/hr)
As to calculate for 9 sec I am converting the whole things to seconds
(i.e.)speed=60000/3600=16.666666(remember this is for one second)

therefore for 9 seconds
16.666666*9= 150

@Contactjerin

Feet to Meter conversion: 1 feet = 0.3048 meter
Meter to Feet conversion: 1 meter = 3.28083 feet

This is what I mentioned already in this discussion.

You can easily find the answer for your question that is:

3.28083 feet = 1 meter.

Any one know the how many feet is one meter?

Let length of the train be 'x' metres...
Speed of the train = 60km/hr(given)
Time = 9seconds(given)

refer the formulas for train problems...

As the time is given in seconds and answers are given in metre(train length) we are in need to convert from km/hr to m/s
km/hr = 1000m/(60min*60sec) = 5/18 m/s

Length of the train(distance covered a post)= speed * time
= (60*(5/18))*9
= (50/3)*9
= 150 m

For the train related formulas,check the READ MORE in Left corner(Important formulas)...

@Rita

Please explain this problem I am not understand.

Hi good morning this problem am not understand please explain me.

1 mile=1.61 km

Why se converting m/sec into km/sec?

v=d/t means
velocity=distance/time

It's is very nice process to do this problem.
