0.833 m/s

Explanation:

First you need to understand what 3 km per hour means.

In 1 hour the distance covered is 3km

However, we want to change to metres.

Knowing that 1 km = 1000 m gives us:

In 1 hour the distance covered is 3km
In 1 hour the distance covered is 3000 ×1000

In 1 minute you will cover160 of the distance in an hour

In 1 second you will cover 160 of the distance in a minute.

3km/hour=3×100060×60m/s ×1000÷3600

=0.833m/s

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To convert from m/s to km/h you will do exactly the opposite:

m/s to km/h ×36001000=×3.6

km/h to m/s ×10003600=÷3.6

You can easily learn these short cut calculations.

3km/h => 3000m/h

i.e. 3000÷(6060)m/s

=> (3000÷3600)m/s

or, (5÷6)m/s

i.e. 0.83333m/s
