Speed, Distance, and Time Problems

The video tutorial explains how to determine how much a driver exceeded the speed limit. It starts by setting up the problem, where a man drove 350 miles in 4.5 hours with a speed limit of 65 mph. The tutorial then walks through calculating the driver's speed by dividing the distance by time, adjusting decimals for easier division, and using a calculator to find the approximate speed. Finally, it concludes by subtracting the speed limit from the calculated speed to find the excess speed, which is approximately 13 mph over the limit.
