Answer 1

28 miles E

Step-by-step explanation:

Given parameters:

Distance due east = 40miles

Distance due west = 12miles

Unknown:

Displacement = ?

Solution:

Displacement is the distance with a specified direction. It only considers the initial and final points.

Displacement = Final distance - Initial distance

Displacement = 12miles - 40miles

Displacement = - 28miles

The negative 28miles shows that the car is moving east ward.
