Average speed =80km/1.5hr=53.33km/hrs
The question did not include the output to be produced. However, below are the outputs.
My age is 21
Twice my age is 42
Three times my age is 63
ANSWER:
public class NewClasss{
public static void main(String[] args) {
int x,y,z;
x = 21;
y = 2*x;
z=3*x;
System.out.println("My age is " + x);
System.out.println("twice my age is " + y);
System.out.println("three times my age is " + z);
}
}
Answer:
Yes the statement is true.
Explanation:
Power is defined as the rate at which energy is transferred by an object on account of work done.
Mathematically

An object that does work loses it's energy while an object on which work is done gains energy.
Power is often dependent on the type of energy transfer thus we have Electrical Power, Mechanical Power depending on the type of energy involved in the system.
Concept of power is important since it gives us a measure of how fast energy can be derived to given to a system.
