Correct Answer

Explanation


Distance = 1500 meters
Time = 1 minute 20 seconds = 80 seconds

Required speed = distance/time = 1500 meters / 80 seconds = 75/4 m/s

To convert the speed from m/s to km/hr, we use the conversion factor: 1 m/s = 18/5 km/hr

Speed in km/hr = (75/4 m/s) * (18/5 km/hr/m/s) = (75/4) * (18/5) = (225/20) = (45/4) = 11.25 km/hr * (4/3) = 15/3 km/hr = 5 km/hr * 3 = 15 km/hr = 67.5 km/hr.
