Answer 2

Problem Analysis

We are given that two trains start from different stations and travel towards each other. The distance between the stations is 385 km, and the trains meet after 5 hours. We need to find the speed of the second 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 using this formula.

Calculation

Given: - Distance between the stations = 385 km - Time taken to meet = 5 hours

Using the formula Speed = Distance / Time, we can calculate the speed of the second train:

Speed = 385 km / 5 hours

Calculating the speed:

Speed = 77 km/h

Therefore, the speed of the second train is 77 km/h.

Answer

The speed of the second train is 77 km/h.
