Answer: 3.33 m/s
Explanation:
Assuming the questions is to convert 12 km/h to meter per second (m/s), let's begin:
In order to make the conversion, we have to know the following:
[tex]1 km=1000 m[/tex]
And:
[tex]1 h=3600 s[/tex]
Keeping this in mind, we can make the conversion:
[tex]12 \frac{km}{h} \frac{1000 m}{1 km} \frac{1h}{3600 s}[/tex]
Then:
[tex]12 \frac{km}{h}= 3.33 \frac{m}{s}[/tex]
