Answer:
Options A and D are correct choices.
Step-by-step explanation:
We are asked to convert 18 cm/s to meters per minute.
We know that 1 m equals 100 cm and 1 minute equals 60 seconds.
\(\frac{\text{18 cm}}{\text{sec}}\times \frac{1\text{ m}}{\text{100 cm}}\times \frac{60\text{ sec}}{\text{1 min}}\)
Therefore, our required expressions are \(\frac{1\text{ m}}{\text{100 cm}}\) and \(\frac{60\text{ sec}}{\text{1 min}}\).
