<image>On a straight highway, there are three locations: \( A \), \( B \), and \( C \). Location \( C \) is situated between locations \( A \) and \( B \). Cars X and Y depart from locations \( A \) and \( B \) respectively, traveling at a constant speed along the highway until they reach location \( C \), where they stop. During Car X's journey from \( A \) to \( C \), the function relating the distances \textit{\( y \)} (in km) from each of the cars to location \( C \) and the travel time \textit{\( t \)} (in hours) of Car X is represented in a graph. When the two cars are \( 350 \) km apart, \textit{\( t \)} = _ _ __ h
