सुपरफास्ट ट्रेन और सुरंग... (Superfast train and the tunnel...)

विशेष नोट : अगर आप जवाब ढूंढ लेते हैं तो ठीक, वरना कमेंट लिख दीजिएगा, मैं जवाब आपको मेल के जरिये भेज दूंगा...

ठीक एक किलोमीटर लंबाई वाली एक सुपरफास्ट ट्रेन को ठीक 20 किलोमीटर लंबी एक सुरंग को पूरी तरह पार करने में कितना समय लगेगा, यदि वह 105 किलोमीटर प्रति घंटे की समान गति से चल रही हो...?

Now, the same riddle in English...

Special Note: If you succeed in solving this one, well and good; but in case, you don't, just leave a comment, and I will mail the answer to you...

How long will it take for an exactly one-kilometer-long superfast train to completely pass through an exactly 20-kilometer long tunnel, if the uniform speed of the train is 105 KMPH...?

    Mr Super Bazar, I am sorry to inform you, but the answer is not right... Please try once again...

    And as far as putting the answers on the blog is concerned, I think if one gets the answers, he does not really try to solve the riddles... So, in my opinion, it is always better not to put the answers with the questions... So, if you try and unfortunately can't find the answer, let me know, and I will mail it to you... :-)

    प्रकाश भाई, जिस दिन की बात मैंने इस पहेली में की, उस दिन मौसम भी ठीक रहा, और ड्राइवर भी नशे में नहीं था, सो, आपका जवाब भी ठीक है... बधाई... :-)
