1. The problem involves understanding the speed given as 8 cm/s instead of 9 cm/s. 2. Speed is defined as the distance traveled per unit time, expressed as $\text{speed} = \frac{\text{distance}}{\text{time}}$. 3. If the speed is 8 cm/s, it means the object moves 8 centimeters every second. 4. This correction affects any calculations involving distance or time where speed is a factor. 5. For example, if you want to find the distance traveled in $t$ seconds, use $\text{distance} = \text{speed} \times t = 8 \times t$ cm. 6. Always ensure to use the correct speed value in your formulas to get accurate results.
