Answer 2

Train stops an average of 12 min per hour .

Given :

Average speed of train without stopping , 65 km/hr .

Average speed of train with stoppage , 52 km/h .

Therefore , due to stoppage the train travels 13 km less in an hour .

Time taken to cover 13 km , $\dfrac{13}{65}\ hours=\dfrac{13}{65}\times 60 =12\ min\ .$

Therefore , train stops an average of 12 min per hour .

Hence , this is the required solution .
