Question

An object moves from point $A$ to point $B$ to point $C$, then back to point $B$ and then to point $C$ along the line shown in the figure. Find the distance covered by the moving object in $\text{km}$.

• A. 13
• B. 15
• C. 17
• D. 19

Answer 1

The correct option is C 17

Distance covered is equal to the path length that the particle covers.
Distance $=AB+BC+CB+BC$
$=5+4+4+4=17\text{km}$
