Correct Answer: 92.8 km/hr

Solution : Time to travel from place X to place Y = 4 hours
Speed when travelling from place X to place Y = 80 km/hr
Distance from place X to place Y = 4 × 80 = 320 km
Time to travel from place Y to place Z = 1 hour
Speed when travelling from place Y to place Z = 80 × 180% = 144 km/hr
Distance from place Y to place Z = 144 × 1 = 144 km
Average speed = $\frac{\text{total distance}}{\text{total time}}$ = $\frac{320+144}{4+1}$ = $\frac{464}{5}$ = 92.8 km/hr
Hence, the correct answer is 92.8 km/hr.
