A map has a scale of $1:2,000,000$ and on the map, there are several cities with distances as follows:

• City $A$ to city $x$ = $2.5 \text{ cm}$
• City $x$ to city $B$ = $3 \text{ cm}$
• City $A$ to city $y$ = $4 \text{ cm}$
• City $y$ to city $B$ = $4.5 \text{ cm}$

Benu and Mamang will travel from city $A$ to city $B$ via different routes. Benu takes the route passing through city $x$, while Mamang passes through city $y$.
