The video tutorial discusses a problem from class 9 science, chapter 7 on motion. It involves a train starting from rest and reaching a velocity of 72 km/h in 5 minutes. The tutorial is divided into two main parts: calculating the acceleration and the distance traveled by the train. The instructor explains the conversion of units and uses formulas to find the acceleration and distance. The acceleration is found to be 1/15 m/s², and the distance traveled is 3 km. The video concludes with a summary of the results.
