Solve the below given problem:
A vehicle moves along a straight line and covers a distance of \(2\ km\). In the first \(500\ m\), it moves with a speed of \(10\ m/s\) and in the next \(500\ m\), it moves with a speed of \(5\ m/s\). With what speed should it move the remaining distance so that the journey is complete in 207 \(s\)? What is the average speed of the vehicle for the entire journey?
1. Speed of the remaining distance \(=\) \(m/s\)
2. Average speed of the entire journey \(=\) \(m/s\)
[Note: Enter the answer in two decimal values]
