Question

In a rubber duck race, the winning duck traveled 300 meters in 10 minutes. What was the duck's average speed?

Answer 1

30 miles is the answer

Answer 2

$300 \div 10 = 30$
In minutes form, duck's average speed is 30 meters per minute.

$300 \div (10 \times 60) \\ = 300 \div 600 \\ = 0.5$
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
