Answer:

The resultant vector is
$\overrightarrow{AB}-\overrightarrow{BC}$ . The resultant displacement is 1 miles.

Explanation:

It is given that Minossoo is training for cross country in the fall. He ran 5 miles east. Then he turned around and ran 4 miles west.

Let he start from point A, then ran 5 miles east and reach to point B. After that he turned around and ran 4 miles west to reach point C.

$|\overrightarrow{AB}|=5miles$

$|\overrightarrow{BC}|=4miles$

His initial direction is east, then he turned and run along the west direction. The resultant vector is

$\vec{v}=\overrightarrow{AB}-\overrightarrow{BC}$

The resultant displacement

$\vec{v}=5-4=1$

Therefore resultant vector is
$\overrightarrow{AB}-\overrightarrow{BC}$ . The resultant displacement is 1 miles.
