To isolate distance (d) in the formula for time in terms of distance and velocity, \( t = \frac{d}{v} \), you would need to use multiplication.
To isolate distance, you can rearrange the equation as follows:
- Start with the formula: \( t = \frac{d}{v} \)
- Multiply both sides by \( v \): \( t \cdot v = d \)
So, the correct answer is multiplication.
