Given the definition of the Vehicle class:

Class Vehicle {  
int distance;  
Vehicle (int x) {  
this distance = x;  
}  
public void increSpeed(int time) {  
int timeTravel = time; //line n1  
//line n3  
class Car {  
int value = 0;  
public void speed () {  
value = distance /timeTravel; //line n2  
System.out.println ("Velocity with new speed"+value+"kmph");  
}  
}  
speed(); //line n3  
}  
}  
and this code fragment:  
Vehicle v = new Vehicle (100);  
v.increSpeed(60);

What is the result?

Given the code fragment:
Path source = Paths.get ("/data/december/log.txt");
Path destination = Paths.get("/data");
Files.copy (source, destination);
/data/december/log.txt is accessible and contains:
and assuming that the file

What is the result?
log.txt is created in the /data directory and the content of the /data/december/log.txt file is copied to it.
