Driving Speed and Time Calculations

The video tutorial explains how to calculate the time saved by driving from Phoenix to San Diego at 85 mph instead of the speed limit of 65 mph. It uses the formula distance equals rate times time, rearranged to solve for time. The tutorial calculates the travel time for both speeds, determines the time saved, and converts it to minutes. It concludes with a note on the risks of speeding.
