Correct Answer: 42 km/hr
Solution : Given: A person covers the first 25 km in 60 minutes and the next 38 km in 30 minutes. Total distance = 25 + 38 = 63 km Total time = (60 + 30) = 90 minutes = $\frac{90}{60}$ = $\frac{3}{2}$ hours So, the average speed = $\frac{63}{\frac{3}{2}}$ = $63×\frac{2}{3}$ = 42 km/hr Hence, the correct answer is 42 km/hr.
