Concept explainers
Most experienced runners get to a point where they can comfortably jog long distances at a consistent pace. This “pace,” of course, is another way to say “rate of change,” because speed is the rate at which distance changes compared to time. One particular runner jogs one lap around a 400-meter track in 2 minutes. In Questions 7–16, you can assume that the runner can maintain this pace for a long time.
What would this runner’s total time be for a 10k race? (Ten kilometers, that is. Recall that
