Question

Shalloo ran $20m$ to the east, then she turned left and walked for $15m$, then turned right and went $25m$ and then turned right again and ran $15m$. How far was Shalloo from the starting point?

• A. $45$ $m$
• B. $35$ $m$
• C. $25$ $m$
• D. $15$ $m$

Answer 1

The correct option is A $45$ $m$

Let us consider a Cartesian plane thinking positive X-axis as East; negative X-axis as West; positive Y-axis as North and negative Y-axis as South.

Shalloo ran $20m$ on +ve X-axis then $15m$ parallel to +ve Y axis. From there $25m$ parallel to +ve X axis. Again, $15m$ parallel to -ve Y axis. Finally, she would be on +ve X-axis at a distance of $20+25=45m$ from origin.

Therefore, Option $A$ is correct.
