To calculate the speed of the object, you can use the formula for speed:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the object travels 10 centimeters in 2 seconds. Plugging the values into the formula gives:
\[ \text{Speed} = \frac{10 \text{ cm}}{2 \text{ sec}} = 5 \text{ cm/sec} \]
However, since 5 cm/sec is not one of the provided options, let's verify the calculations.
The distance is 10 cm and the time is 2 seconds, so recalculating:
\[ 5 \text{ cm/sec} \]
This indicates that either the options do not include the correct answer or there was a misunderstanding in the question or choices. Based on the calculations, the speed of the object is indeed 5 cm/sec, which is not among the responses provided.
Thus, the answer is not present in the options listed.
