Answer:
The average velocity is 180 km/hr
Explanation:
Given;
initial velocity, u = 60 km per hour
final velocity, v = 120 km per hour
initial time = 1 hour
final time = 2 hour
Initial position = 60 km/h x 1 hour = 60 km
final position = 120 km/h x 2 hour = 240 km
The average velocity is given by;
![V_{avg} = \frac{Final \ position\ - \ Initial \ position}{final \ time\ - \ initial \ time}\\\\V_{avg} = \frac{240km \ - \ 60km}{2hr\ - \ 1hr} \\\\V_{avg} = \frac{180 \ km}{1hr} \\\\V_{avg}= 180 \ km/hr](https://tex.z-dn.net/?f=V_%7Bavg%7D%20%3D%20%5Cfrac%7BFinal%20%5C%20position%5C%20%20-%20%5C%20Initial%20%5C%20position%7D%7Bfinal%20%5C%20time%5C%20%20-%20%5C%20initial%20%5C%20time%7D%5C%5C%5C%5CV_%7Bavg%7D%20%3D%20%5Cfrac%7B240km%20%5C%20-%20%5C%2060km%7D%7B2hr%5C%20%20-%20%5C%201hr%7D%20%5C%5C%5C%5CV_%7Bavg%7D%20%3D%20%5Cfrac%7B180%20%5C%20km%7D%7B1hr%7D%20%5C%5C%5C%5CV_%7Bavg%7D%3D%20180%20%5C%20km%2Fhr)
Therefore, the average velocity is 180 km/hr
The correct answer among the choices is option D. Density is not one of the properties included in the ideal gas law. The law is expressed as: PV=nRT. As we can see, the pressure, the volume and the temperature of the gas are included in the law.
