Explanation:

- Let the train’s speed be x km/hr.

- The car is 20% slower, so its speed = 0.8x km/hr.

- Both start together, cover 240 km, and reach at the same time.

- The train stops for 48 minutes (which is 0.8 hours) during the journey.

- Time taken by the train (including stoppage): \( \frac{240}{x} + 0.8 \) hours.

- Time taken by the car: \( \frac{240}{0.8x} \) hours.

- They reach together: \( \frac{240}{0.8x} = \frac{240}{x} + 0.8 \)

- Simplifying:

- \( \frac{240}{0.8x} - \frac{240}{x} = 0.8 \)

- \( \frac{240}{0.8x} - \frac{240}{x} = 0.8 \)

- \( 300/x - 240/x = 0.8 \) (since 240/0.8x = 300/x)

- \( (300-240)/x = 0.8 \)

- \( 60/x = 0.8 \)

- \( x = 75 \) km/hr (train’s speed)

- Car’s speed = 0.8 × 75 = 60 km/hr

- Among the options:

- Option 1: 80 (too high)

- Option 2: 100 (too high)

- Option 3: 120 (too high)

- Option 4: 60 Correct Answer
