# What is the speed of an object that travels from ( 6, -2, 3)  to ( 7,-3,6 )  over 3 s?

$v = \frac{\sqrt{12}}{3} \frac{m}{s}$
average speed

#### Explanation:

$v = \frac{s}{t}$
$s = \sqrt{{\left(x - {x}_{1}\right)}^{2} + {\left(y - {y}_{1}\right)}^{2} + {\left(z - {z}_{1}\right)}^{2}}$
s=sqrt((6-7)^2+(-2-(-3))^2+(3-6)^2
$s = \sqrt{12}$
$v = \frac{\sqrt{12}}{3} \frac{m}{s}$
