the time taken will be 1 minute.
as first the engine of train enters and then the whole train passes and finally the last point in the train crosses the bridge.
So, total distance covered by the train = Length of bridge + it's own length
=> (200+400)m
=> 600 m.
Speed = 36 kmph = 10m/s
Hence, time taken = 600/10 s = 60s = 1min

D=200 m+400 m=600 m
S=36km/h=36×5÷18=10 m/sec
T=?
T=D÷S
T=600÷10
T=60 sec
i hope this may help u.

i hope this may help u.
bcoz it is the formula that we have to change the km/h into m/sec in this question ok
K thank
thanks a lot @chayonika :D
actually ur comment is the best. sorry i cudn't do dat becoz i hv started only. :( :)
Conversion of km/hr to m/s : .........................................................................................................................................................km /hr = 1000 metres / 60 minutes = 1000 meters / 60*60 seconds = 1000 meters / 3600 seconds = 10 meters/36 seconds = 5metres /18 seconds = 5/18 m/s .. hope you understood the conversion!
To whom u r asking @ gashu
yea i knw dat :) my teacher taught me today and thank u for gvng me the ans :)
@shruti I just wrote it .. @durga thanks
K because I too asked about it so only@gashu
