Question

Olive walks 20 yd towards the north. She then turns left and walks 40 yd. She again turns left and walks 20 yd. She again moves 20 yd after turning to the right.
How far is she from her original position?

• A. 40 yd
• B. 20 yd
• C. 50 yd
• D. 60 yd

Answer 1

The correct option is D 60 yd

Let's assume that Olive is standing at point P as shown below.

From there, let's follow the directions as given in the question:


So, Olive will end up at point X.

Clearly, Olive's distance from their initial position is the length of the line segment PX.

The value of PX is:
PX = PS + SX

= QR + SX

= (40 + 20) yd

= 60 yd

Hence, Olive is 60 yd away from her initial position.
