To find the speed of the object, you can use the formula for speed, which is:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the distance is 10 centimeters and the time is 2 seconds. Plugging in the values:
\[ \text{Speed} = \frac{10 \text{ cm}}{2 \text{ sec}} = 5 \text{ cm/sec} \]
However, 5 cm/sec is not one of the response options you provided. Can you please double-check the values given or specify if there's additional information?
