A bird is flying with a speed of 40 km/hr. in the north direction. A train is moving with a speed of 40km/hr. in the west direction. A passenger sitting in the train will see the bird moving with velocity:-

A train 100m in length, is moving with a velocity of 54km/hr in one direction, Another train, 80m in length, is moving with a velocity of 36km/hr in the opposite direction. Find the time when the two trains will completely cross each other.

A train moving with a speed of 36 km/hr takes 14 sec to cross a bridge of length 100 m. The length of the train is

A bird is flying towards south with a velocity 40km/h and a train is moving with a velocity 40 km/h towards east. What is the velocity of the bird w.r.t. an obserber in the train ?

A bird is flying towards south with a velocity 40km/hr and a train is moving with a velocity 40km/hr towards east. What is the velocity of the bird w.r.t. an obserber in train:-

A bird is flying towards south with a velocity 40km/hr and a train is moving with a velocity 40km/hr towards east. What is the velocity of the bird w.r.t. an obserber in train:-

Two trains A and B moving with speed 36 km/hr and 72 km/hr resp. in opposite direction. A Man moving in train A with speed 1.8 km/hr opposite to direction of train. Find velocity of man as seen from train B (in m/s)

Two trains A and B moving with speed 36 km/hr and 72 km/hr resp. in opposite direction. A Man moving in train A with speed 1.8 km/hr opposite to direction of train. Find velocity of man as seen from train B (in m/s)

A train travels at a speed of 40 km/hr and another train at a speed of 20 m/s. What is the ratio of speed of the first train to that of the second train?
