Quizplus · Accepted Answer

Since speed is inversely proportional to time for a fixed distance, if the time increases from 20 minutes to 30 minutes (which is a 1.5 times increase), the speed must decrease by the same factor to cover the same distance. Therefore, 60 miles per hour divided by 1.5 equals 40 miles per hour.
