A man travels 4km due north,then travels 6km due east and further travels 4km due north .how far he is from the starting point.
so now he's 8km N and 6km E
The distance is the hypotenuse, so he's 10km away.
A plane left a town and travelled 96km on the bearing of 045. Tt then went southwards until it was 96km from the starting point. How far southward did it to the nearest km?
