Can you go 500 km in 8 hours without driving faster than 55 mph?

No, you cannot travel 500 km in 8 hours without exceeding a speed of 55 mph. To determine the necessary speed, convert 500 km to miles (approximately 311 miles). Dividing 311 miles by 8 hours gives a required speed of about 38.875 mph, which is below 55 mph. Thus, it is indeed possible to cover that distance within the time limit without exceeding the speed.
