Problem Analysis

We are given that a bus and a car start simultaneously from the same city in opposite directions. The bus is traveling at a speed of 50 km/h, and the car is traveling at a speed of 80 km/h. We need to find the following:

1. The relative speed of the bus and the car. 2. The distance between the bus and the car after 3 hours.

Solution

1. The relative speed of the bus and the car is the sum of their individual speeds. Therefore, the relative speed is 50 km/h + 80 km/h = 130 km/h. 2. To find the distance between the bus and the car after 3 hours, we can multiply the relative speed by the time traveled. Therefore, the distance between them is 130 km/h * 3 hours = 390 km. Therefore, after 3 hours, the bus and the car will be 390 km apart from each other.

I hope this helps! Let me know if you have any further questions.
