This problem involves finding the total displacement of a car that travels 35 km North and then 20 km East.

Displacement is a vector quantity, which means we can use the Pythagorean theorem to find the straight-line distance from the starting point to the final position of the car.

The formula is: $d = \sqrt{{(35^2 + 20^2)}}$ Now, let's calculate it:

$d = \sqrt{{35^2 + 20^2}} = \sqrt{{1225 + 400}} = \sqrt{{1625}} \approx 40.3 \, \text{km}$

So, the total displacement of the car is approximately 40.3 km.

Here are 5 related questions for practice:

1. What would the displacement be if the car traveled 30 km North and 40 km East?
2. How would you calculate displacement if the car traveled 50 km South and 30 km West?
3. What is the difference between distance and displacement in this context?
4. How would displacement change if the car returned to its starting point?
5. Can you find the angle between the displacement and the North direction?

Tip: Displacement is always a straight-line distance from the starting point, regardless of the path taken.
