Question

Calculate the speed and velocity for a car that went a distance of 12.5 km west in 2 hours. (Please show the solution)

Answer 1

Given:

$d=12.5\:\rm km \; (to \;the\; west )$

$t=2\:\rm hr$

The speed (magnitude of the velocity)

$$v=\frac{d}{t}=\frac{12.5\:\rm km}{2\;\rm hr}=6.25\:\rm km/h$$

The velocity

$$6.25\:\rm km/h \; (to \;the\; west )$$
