Correct Answer: 90 km/hr


Solution : Total time travelled by the thief = 9:00 - 8:15 = 45 min = $\frac{3}{4}$ hour
Speed of thief = 60 km/hr
Distance travelled = 60 × $\frac{3}{4}$ = 45 km
Total time travelled by the thief = 9:00 - 8:30 = 30 min = $\frac{1}{2}$ hour
Speed of police = $\frac{45}{\frac{1}{2}}$ = 90 km/hr
Hence, the correct answer is 90 km/hr.
