Correct Answer: 5 hours
Solution :
The distance can be calculated using the formula:
Distance = Speed × Time.
Given: Speed is 60 km/h and the time is 4.5 hours (4 hours 30 minutes).
Distance = 60 × 4.5 = 270 km
The speed is changed to 15 m/s = $\frac{18}{5}×15=54$ km/h.
Time = $\frac{\text{Distance}}{\text{Speed}} = \frac{270}{54} = 5$ hours
Hence, the correct answer is 5 hours.
