To find the speed \( v \) that Amelia needs to travel at, we can start from the formula \( d = vt \), where:
- \( d \) is the distance
- \( v \) is the speed
- \( t \) is the time
We want to rearrange this formula to solve for \( v \). To do this, we can divide both sides of the equation by \( t \):
\[ v = \frac{d}{t} \]
Now, we can substitute in the values that we have:
- \( d = 388 \) miles (the distance)
- \( t = 7 \) hours (the time)
So, the rearranged formula to highlight the quantity of interest is:
\[ v = \frac{388}{7} \]
