Question

A ship sails 60 km due north ,then 20 km due west and finally 39 km due south How far is it from it's starting point

Answer 1

Answer:

It is 29km towards north west from the starting point.

Step-by-step explanation:

The ship moves north followed by west and then south. It moves 60km towards the north but 39km towards the south so it is in the north west direction from the starting point.

In order to find the distance, we form an imaginary triangle and then calculate the hypotenuse.

One side of the triangle= 60-39 = 21km.

Another side= 20km

Distance^2 = 21^2 + 20^2 = 841

So, distance = √841 = 29km.

Answer 2

Answer:

The ship is 29 km to the North- West from the starting point.
