Answer: 3.33 m/s
Step-by-step 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:
![1 km=1000 m](https://img.qammunity.org/2020/formulas/geography/college/lqbr8ba404c3kl9za2amyx7jczkjg4a3e3.png)
And:
![1 h=3600 s](https://img.qammunity.org/2020/formulas/physics/middle-school/2hututyshz1q46qeq5qbyoo8uof90u9ow2.png)
Keeping this in mind, we can make the conversion:
![12 (km)/(h) (1000 m)/(1 km) (1h)/(3600 s)](https://img.qammunity.org/2020/formulas/physics/middle-school/ysxx4l8oofxzlflvgv8y5dfvyfbqcfjlfa.png)
Then:
![12 (km)/(h)= 3.33 (m)/(s)](https://img.qammunity.org/2020/formulas/physics/middle-school/lryzqhmnfoifna8qdwwlq6i18iqnmgd9ks.png)
