Question

A sailboat travels 15 km [E] and then 11 km [W]. What is the boat's final position?A. 26 kmB. 26 km [E]C. 26 km [W]D. 4.0 km [E]

Answer 1

We will have the following:

First, we will assume that movement to the east is a positive value and movement to the west is negative, so:

`d=15-11\Rightarrow d=4`

So, the boat's final position is 4.0 km east.
