A train is moving at a speed of 72 km/h and covers a certain distance in 6 hours. If the same distance is to be covered in 8 hours, then what will be the speed (in km/h) of the train?

Options

A. 45
B. 54
C. 63
D. 64

Answer

To solve the problem, we need to find the speed of the train when covering the same distance in 8 hours instead of 6 hours.

### Step-by-Step Solution:

1. **Determine the distance covered in 6 hours at 72 km/h:**
- Distance = Speed × Time
- Here, Speed = 72 km/h and Time = 6 hours.
- Distance = 72 km/h × 6 hours = 432 km.

2. **Determine the speed required to cover the same distance in 8 hours:**
- We already calculated the distance as 432 km.
- Now, we need to find the speed when the time is 8 hours.
- Speed = Distance / Time
- Speed = 432 km / 8 hours = 54 km/h.

### Final Answer:
The speed of the train when covering the same distance in 8 hours will be **54 km/h**.
