Problem Analysis

We are given that two trains start simultaneously from two cities and meet after 6 hours. The speed of one train is 52 km/h, and the speed of the other train is 67 km/h. We need to find the distance between the two cities.

Solution

To find the distance between the two cities, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each train and then find the total distance between the two cities.

1. Train A: - Speed of Train A = 52 km/h - Time = 6 hours - Distance traveled by Train A = Speed × Time = 52 km/h × 6 hours = 312 km

2. Train B: - Speed of Train B = 67 km/h - Time = 6 hours - Distance traveled by Train B = Speed × Time = 67 km/h × 6 hours = 402 km

3. Total distance between the two cities: - Total distance = Distance traveled by Train A + Distance traveled by Train B = 312 km + 402 km = 714 km

Therefore, the distance between the two cities is 714 km.

Answer

The distance between the two cities is 714 km.
