Correct Answer: 16 km/hr


Solution : Given: A car covers the first 140 km of a journey in 10 hours and the next 260 km in 15 hours.
Total distance = 140 + 260 = 400 km
Total time = 10 + 15 = 25 hours
So, the average speed = $\frac{\text{Total distance}}{\text{Total time}}=\frac{400}{25}=16$ km/hr
Hence, the correct answer is 16 km/hr.
