(Solve this Hurdle by 18th March.)
Q1. A train 600 meters long is traveling at a speed of 30 Mt/ Sec. The train enters a tunnel of length 2.1 Km . How much time will the train take to be completely out of the tunnel.
Q2. Train A when going from X to Y takes 20 sec to pass Train B. Train A takes the same time at the same speed to pass Train B when it is going from Y to X. Which of the following is true:
1) The speed to train B was reduced.
2) The speed of train B remains unchanged.
3) The speed of train B was increased.
4) This is not possible.
Q3. Which of the following is true :
a) Two trains of different length with different but constant speeds can take less time to cross each other when moving in same direction and more time when traveling in opposite direction.
b) Two trains of different length traveling at same constant speed will be able to cross each other after a certain time when moving in same direction.
c) Two trains of same length are traveling at same constant speed. The ends of the two train will be maximum apart from each other when the trains are traveling in 90 degrees to each other. (UrPercentile.com)
d) There are two trains A and B with speed C and D respectively. They take X and Y time to pass each other when moving in same direction and in opposite direction respectively.
