A goods train of length 500 m transverse a 2-km-long tunnel at a constant speed of 36 km/hour. The time needed for the train to completely pass through the tunnel is

  1. 3 minutes 20 seconds

  2. 4 minutes 10 seconds

  3. 4 minutes 40 seconds

  4. 6 minutes 10 seconds


Correct Option: B

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance traveled by him is :

  1. 50 km

  2. 56 km

  3. 70 km

  4. 80 km


Correct Option: A
Explanation:

Let the actual distance travelled be x km.
Then, $\dfrac{x}{10}=\dfrac{x+20}{14}$

$14x=10x+200$
$4x=200$
$x=50 km$
