To find the speed (v) that Amelia needs to travel, we can start with the formula for distance:

\[ d = vt \]

Where:

  • \( d \) is the distance (388 miles)
  • \( v \) is the speed in miles per hour (the quantity of interest)
  • \( t \) is the time in hours (7 hours)

To solve for \( v \), we can rearrange the formula:

  1. Divide both sides of the equation by \( t \):

\[ v = \frac{d}{t} \]

Now, we have the formula rearranged to highlight the quantity of interest, which is the speed \( v \):

\[ v = \frac{d}{t} \]

This means the speed is equal to the distance divided by the time required.
