Given some data, compute the average speed.
The average speed can be calculated by dividing the total distance traveled by the time taken. In this case, the distance traveled is 200 km and the time taken is 4 hours. Therefore, the average speed is 200 km / 4 hours = 50 km/hour.
Distance traveled: 200 km, Time taken: 4 hours
