Let's break this down step-by-step.
(a) Writing the Equation
Let:
- \( d \) be the distance around the track (in kilometers).
- \( n \) be the number of times Amy drove around the track.
- \( D \) be the total distance driven (in kilometers).
The relationship between these quantities can be expressed as: \[ D = n \cdot d \]
In this case, we fill in the blanks with:
- The letter \( d \) (for distance around the track),
- The number \( n \) (for the number of laps), and
- The number \( D \) (for the total distance).
So, the equation can be written as: \[ D = n \cdot d \]
(b) Solving for \( d \)
To solve for \( d \), we rearrange the equation: \[ d = \frac{D}{n} \]
This means that the distance around the track can be found by dividing the total distance by the number of laps.
If you provide specific values for \( D \) and \( n \), I can help further by calculating the exact distance \( d \).
