Answer 2

Answer:

The correct answer will be -

John's total displacement will be 145 miles North.

Explanation:

Given in the question -

• John travels 250 miles to the North.
• After that he back-track to the south for 105 miles to pick up a friend.

We have to calculate John's total displacement.

we know that displacement is the shortest distance between the initial point and the final point.

Now,

Let he was at some point which is the origin. From there He goes 250 miles North. His displacement is -

$displacement = 250\ miles\ North$

Now he backtracks then displacement will be -

$= 250 \ miles \ North - 105\ miles\ South\\\\= 145 \ miles \ North$

So his final displacement will be 145 miles North.
