Problem Analysis

Two buses are traveling towards each other from two different cities. The distance between the cities is 406.2 km. The first bus is traveling at a speed of 53.82 km/h, and the second bus is traveling at a speed of 45.7 km/h. After the first bus has traveled 269.1 km, it meets the second bus. We need to find out how many hours earlier the first bus left compared to the second bus.

Solution

To solve this problem, we can use the formula: time = distance / speed

First, we'll calculate the time taken by the first bus to meet the second bus. Then, we'll use this time to find out how many hours earlier the first bus left compared to the second bus.

Calculations

1. Time taken by the first bus to meet the second bus: - Time = Distance / Speed - Time = 269.1 km / 53.82 km/h - Time = 5 hours

2. Now, we'll calculate the time taken by the second bus to cover the same distance: - Time = Distance / Speed - Time = 406.2 km / 45.7 km/h - Time = 8.88 hours

3. Finally, we'll find out how many hours earlier the first bus left compared to the second bus: - Difference in time = Time taken by the second bus - Time taken by the first bus - Difference in time = 8.88 hours - 5 hours - Difference in time = 3.88 hours

So, the first bus left 3.88 hours earlier than the second bus.

Answer

The first bus left 3.88 hours earlier than the second bus.
