A train approaches a tunnel AB, Inside the tunnel a goat located at a point i.e., 5/12 of the distance AB measured form the entrance A. When the train whistles, the goat runs. If the goat moves to the entrance of the tunnel A. The train catches the goat exactly at the entrance. If the goat moves to the exit B, the train catches the goat exactly at the exit. Find the ratio of speed of train and goat.

A train approaches a tunnel AB. Inside the tunnel a cat located at a point i.e., 5/12 of the distance AB measured from the entrance A. When the train whistles, the cat runs. If the cat moves to the entrance of the tunnel A, the train catches the cat exactly at the entrance. If the cat moves to the exit B, the train catches the cat at exactly the exit. The speed of the train is greater than the speed of the cat by what order?

A train approaches a tunnel AB. Inside the tunnel is a cat located at a point that is 3/8 of the distance AB measured from the entrance A. When the train whistles, that cat runs. If the cat moves to the entrance A of the tunnel, the train catches the cat exactly at the entrance. If the cat moves to the exit B, the train catches the cat at exactly the exit. The ratio of the speed of the train to that of the cat is of the order 3:1 b. 4:1 c. 5:1 d. none of these
