Solution

Let's solve this step by step:

  1. Let's denote the original speed of the train as 'x' km/h. Therefore, the reduced speed of the train is 'x-5' km/h.

  2. The distance covered by the train is the same in both cases, so we can set up the following equation using the formula distance = speed * time:

    x * 45/60 = (x - 5) * 48/60

  3. Simplifying the equation gives:

    3x = 4x - 20

  4. Solving for 'x' gives:

    x = 20 km/h

  5. Now, we can find the distance covered by the train by substituting 'x' into the distance formula:

    distance = speed * time distance = 20 km/h * 45/60 h = 15 km

However, none of the options match this result. There might be a mistake in the problem or the options provided.
