Problem Analysis

We have two trains traveling towards each other from two cities, A and B. The total distance between the two cities is 1467 km. After 9 hours, the trains meet. One train is traveling at a speed of 85 km/h. We need to find the speed of the other train.

Solution

To find the speed of the second train, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the second train.

Calculation

The speed of the first train is given as 85 km/h. The time taken for the trains to meet is 9 hours. The distance between the two cities is 1467 km.

Using the formula, we can calculate the speed of the second train:

Speed of the second train = Distance / Time

Speed of the second train = 1467 km / 9 hours

Calculating the speed of the second train:

Speed of the second train = 163 km/h

Therefore, the second train was traveling at a speed of 163 km/h.

Answer

The second train was traveling at a speed of 163 km/h.
