Question

Answer

Given Data
- Total distance to cover: 52 km
- Time available: 1 hour
- Distance covered at 24 km/hr: 16 km

Calculating the remaining distance and time
- Remaining distance to cover: 52 km - 16 km = 36 km
- Remaining time to cover 36 km: 1 hour - (16 km / 24 km/hr) = 1 hour - 0.67 hour = 0.33 hour

Calculating the speed required for the remaining journey
- Speed = Distance / Time
- Speed = 36 km / 0.33 hour
- Speed = 108 km/hr
Therefore, the person needs to travel at a speed of 108 km/hr for the remaining journey to complete it in the scheduled time of 1 hour. So, option 'A' is the correct answer.
