Beyond the Answer
When measuring time, the most suitable units to use are minutes or hours, as they accurately reflect how long it takes to run a lap. Inches, centimeters, and feet are measurements of distance rather than time and wouldn't make sense in this context. To find the average lap time effectively, the best approach is to randomly pick 40 students to run a lap and measure their times. This method ensures a fair selection and accurately captures each student’s performance, avoiding biases that may arise from self-reported times or volunteer-based methods.
