# An object travels North at 3 m/s for 8 s and then travels South at 4 m/s for  6 s. What are the object's average speed and velocity?

$\text{average velocity=} 0$
$\text{average speed="24/7 " } \frac{m}{s}$

#### Explanation:

$\text{average velocity=} \frac{0}{8 + 6}$

$\text{average velocity=} 0$

$\text{average speed=} \frac{24 + 24}{8 + 6}$

$\text{average speed=} \frac{48}{14}$

$\text{average speed="24/7 " } \frac{m}{s}$
