Two ships are `10km` apart on a line from south to north.The one farther north is moving towards west at `40kmph` and the other is moving towards north at `40kmph`.Then distance of their closest approach is

Two ships are 10 km apart on a line joining south to north. The one farther north is steaming west at 20 km h^-1 . The other is steaming north at 20 km h^-1 . What their distance of closest approach ? How long do they take to reach itb ? .

Two ships A and B are 10 km apart on a line running south to north. Ship A farther north is streaming west at 20 km//h and ship B is streaming north at 20 km//h. What is their distance of closest approach and how long do they take to reach it?

A particle start origin moves towares north with 50m then move towards east with 40m and finaly move towards south with 20m. Find distance and displacement.

A person moves 20 m towards north-east then moves 20 m towards west and then again moves 20 m towards north-east and stops. The magnitude of displacement of the person is:

A partical moves 5M towards east and then 12m towards north. Find the displacement and distance covered.

A person moving on earth's surface starts from north pole & moves 500 km towards south and then moves 1000 km towards east and then again moves 500 km towards north and stops. The displacement of the person is:
