Correct Answer: 100 km


Solution : Speed of train = 50 km/hr
Speed of walking = 10 km/hr
Total time for journey = 12 hours
Let the distance to be covered be $d$ km.
Time taken by train = $\frac{d}{50}$
Time taken by walking = $\frac{d}{10}$
According to the question :
$⇒ \frac{d}{50} + \frac{d}{10} = 12$
$⇒ 6d = 50 × 12$
$⇒ d = 100$ km
Hence, the distance travelled by train is 100 km.
Hence, the correct answer is 100 km.
