 So the way you should solve the question, you should start drawing the right question and then solve it. Others will solve 3-4 questions. You have 90 questions to solve, 2 minutes per question. So if you spend 4 minutes writing the question down in your answer book and then trying to solve it, you spend 10 minutes in a question, that also gets it wrong and others will be solving 4-5 questions at that time. So get this habit of doing things quickly, save your time. So I am reading the question, car A is telling because speed of practice is slower than power. Car A is cars, D and C approach car A in opposing directions, approaching the first car. This car is moving like this. I am reading the question. This is how you come in your exam. You will not ask immediately to explain the question to you. First I can take 2 minutes and then 2 cars, B and C in opposing directions with a speed of 54 km per hour. So B will be, then only C does. So 3 boxes, there are 3 cars. Should I solve? Discuss here. So I discuss it with his capability. It will be 3. Now if the swimmer is someone standing on the back of the car. We will write down the question similar to that. Swimmer can swim with velocity. A swimmer can swim with velocity. His capability is U, a distance D. Upstream then downstream, D distance, both sides. Come back to the same location. Find out the time taken for the swimmer to do so. It is simple step follow. This C. So you have 10 meter per second. And the ball can hit the ground. It can go down also. Like this. And this ball will follow the same path. If it goes up in the end. You need to find out what that will be. I am saying that if they have complete, they can be between. Or they can hit the ground as well. 4 seconds. And now I will be motion inverting, kind of a text one.
