# Question #73a75

Feb 5, 2015

Displacement is dependent on time and velocity.

If I walk to the train station from my home it will take me about 20 minutes to get there.

If I use my bike, I will be there in about 5 minutes.

Conclusion: my velocity on bike is 4 times as high as my walking speed.

It's all in the following formulae:
$s$=displacement, $t$=time and $v$=velocity

$s = v \cdot t$
$v = s / t$
$t = s / v$

In the metric system we use meters, seconds and m/s,
or kilometers, hours and km/h.

You use whichever units you like.
