[tex]300 \div 10 = 30[/tex]
In minutes form, duck's average speed is 30 meters per minute.
[tex]300 \div (10 \times 60) \\ = 300 \div 600 \\ = 0.5[/tex]
In seconds form, duck's average speed is 0.5 meters per second, or 50 cm per second.
P. S. You could choose either seconds form or minutes form.
Hope this helps. - M
