A train travels from City A to City B, a distance of 300 km, at a constant speed of 100 km/h. After a 1-hour stop in City B, it returns at 75 km/h. What is the total travel time, including the stop?
["Total Travel Time from City A to City B and Back: A Clear Breakdown", "Traveling between two major cities is a common journey, and understanding the total travel time helps with planning, logistics, and comfortable travel. In this article, we analyze a straightforward train trip: a train travels 300 kilometers from City A to City B at a steady speed of 100 km/h, stops for 1 hour in City B, then returns at a reduced speed of 75 km/h. We break down the entire journey to calculate the total time, including the stop.", "### The Outbound Journey: City A to City B", "The train travels 300 km at a constant speed of 100 km/h. Using the basic formula:", "[\n\ ext{Time} = \frac{\ ext{Distance}}{\ ext{Speed}} = \frac{300\ \ ext{km}}{100\ \ ext{km/h}} = 3\ \ ext{hours}\n]", "So, the train takes 3 hours to reach City B.", "### The Stop in City B", "Before departing, the train rests for 1 hour.
