Answer 3

Problem Analysis

We have two trains traveling towards each other from two cities that are 500 kilometers apart. The speed of one train is given as 45 kilometers per hour. We need to determine the speed of the second train if the trains meet after 5 hours.

Solution

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

Let's assume the speed of the second train is x kilometers per hour.

The first train travels for 5 hours at a speed of 45 kilometers per hour, covering a distance of 45 × 5 = 225 kilometers.

The second train also travels for 5 hours at a speed of x kilometers per hour, covering a distance of x × 5 = 5x kilometers.

Since the total distance between the two trains is 500 kilometers, we can set up the equation:

225 + 5x = 500

Simplifying the equation:

5x = 500 - 225

5x = 275

Dividing both sides of the equation by 5:

x = 55

Therefore, the speed of the second train is 55 kilometers per hour.

Answer

The speed of the second train is 55 kilometers per hour.
