Problem Analysis

We have two trains traveling towards each other. The speed of one train is 65 km/h, and the speed of the other train is 70 km/h. The trains meet each other after 2 hours. We need to find the distance between the cities.

Solution

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

Distance = Speed x Time

Let's calculate the distance traveled by each train and then add them together to find the total distance.

Train 1: - Speed: 65 km/h - Time: 2 hours - Distance = 65 km/h x 2 hours = 130 km

Train 2: - Speed: 70 km/h - Time: 2 hours - Distance = 70 km/h x 2 hours = 140 km

Total Distance = Distance of Train 1 + Distance of Train 2 = 130 km + 140 km = 270 km

Therefore, the distance between the cities is 270 km.
