To determine how long it will take for Francesca and Mercedes to arrive at the store, you need to find the point where the lines \( F(m) \) and \( M(m) \) intersect on the coordinate plane. The intersection point represents the time at which both will arrive at the store.
To provide an answer, I would need the specific coordinates of the intersection of the two lines, which is typically represented in the form \( (x, y) \). The value of \( x \) usually represents the time, while \( y \) could represent a distance or another variable depending on the context.
If you can share the coordinates of the intersection or describe the graph, I can help you determine the exact time it will take for them to arrive at the store.
