obviously 100km per hour
100km/hour as speed=distance/time therefore 200km/2hour=100km/hour
200 / 4 = 50 Answer: 50 kilometres per hour
The average speed is exactly 200 km per 2.5 hours. As a unit rate, that's equivalent to 80 km/hr.
Average speed = distance/time = 200km/4 hours = 50 km per hour

200km
200km is a distance, not a speed. 200 km/hour is very fast (approximately 125 mph) around double the speed limit on UK mmotorways.
A car that travels 1000 kilometers in 5 hrs, averages 200km/h.
That depends entirely on the speed at which you are driving.
Calculate the total time, and the total distance. Divide the total distance by the total time. This will give you the average speed.
