 Hello and welcome to the session. Let us understand the falling problem today. Formulate the falling problem as a pair of equation and hence find the solution. Given to us as Ruhi travels 300 km to her home, partly by train and partly by bus. She takes 4 hours if she travels 60 km by train and the remaining by bus. If she travels 100 km by train and the remaining by bus, she takes 10 minutes longer. The ideal, we know speed is equal to distance one time and we have to find the speed of the train and the bus separately. Therefore let the speed of the train is equal to u km per hour and speed of the bus is equal to v km per hour. Now let us write the solution. Case 1. When Ruhi travels
