Answer:
see the procedure
Step-by-step explanation:
we have
[tex]12\ \frac{m}{s}[/tex]
Remember that
[tex]1\ km=1,000\ m[/tex]
To convert m to km multiply by (1/1,000)
[tex]1\ min=60\ sec[/tex]
To convert sec to min multiply by (1/60)
substitute
[tex]12\ (\frac{(1/1,000)}{(1/60)})=12(\frac{60}{1,000})=0.72\ \frac{km}{min}[/tex]
