The average velocity is $~97.6 ~m/s~$ to the north The average velocity is $~218.4 ~mi/h~$ to the north
$v_{ave} = \frac{\Delta x}{\Delta t}$ $v_{ave} = \frac{3200~m}{32.8~s}$ $v_{ave} = 97.6~m/s$ The average velocity is $~97.6 ~m/s~$ to the north We can convert the average velocity to units of mi/h: $97.6~m/s\times \frac{1~mi}{1609~m}\times \frac{3600~s}{1~h} = 218.4~mi/h$ The average velocity is $~218.4 ~mi/h~$ to the north.
