 on just relative velocity. So, I will skip the relative velocity question right now, those have done it very well, but we will have a separate discussion on relative velocity. Okay, question number 12, concept, okay, this assignment is for the entire chapter, okay, I will be sending few more, but this concept of entire chapter, in a flight of any discussion. Alright, its average speed time got increased by 30 minutes. Okay, next question, I will make you stand on the bench, then you just put your hands, someone Alright, this is here, a man complete a journey in 10 hours. So, then you talk concept, like this, next 160 kilometer, alright 15, then something, something is not changing in 1, okay, Distance in kilometers, this distance is not much, then going home solving our equation, you will see this difference rising. If you keep on it, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram, Instagram. 40 by 60, this will be good with distance D, next two variables, okay. Listen, it's just 4 hours, I will take lunch just for our teacher. Okay, guys, in 200 minutes, time over the course is how much? Time taken by, at that same point. Right, and what does it mean, 7 seconds? Speed that, speed that, speed that, speed that, speed that, speed that, speed that, speed that, speed that, speed that. And should cover this 35 meter, so speed of D. 200 by, 200 by 5 is whose time? This is time of D. Why, because, easy question, but it was a good question. Sir, last few questions were very easy. Last one. And you took the exam, it will be. The simple questions will be hidden somewhere, you have to find them and solve them first. You don't need to go in sequence like your school exam. Alright, sequence. Just have to solve for, search for the easier one. You know the black hole, so if you guess, I should get it right.
