Answer:

28 miles E

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.
