Question

Anushka starts walking straight towards east. After walking $75$ metres, she turns to the left and walks $25$ metres straight. Again she turns to the left, walks a distance of $40$ metres straight, again she turns to the left and walks a distance of $25$ metres. How far is she from the starting point?

• A. $115\text{m}$
• B. $40\text{m}$
• C. $35\text{m}$
• D. $50\text{m}$

Answer 1

The correct option is C $35\text{m}$

Let us draw the condition of the motion Anushka took
As per the question, we can say that she finally reached to the point $D$ starting from $O$
So, the distance $OD$ is given as $OD=OA-BC=75-40=35\text{m}$
Hence, she is $35\text{m}$ away from the starting point.
