- Use the information about India’s Amiya Kumar Mallick (how far behind he is in distance (m) and time (hundredths of a second) to estimate how fast (meters per second) these world class sprinters are running.
- Create a new speed estimate based on the distance between Usain Bolt and the runner from Tuvalu (the slowest represented in this list).
- Are the two speed estimates the same? Explain why you think this is the case.
- Find a 100m runner from the USN middle school track team. Based on their PR time, estimate how many meters they would finish behind Usain Bolt in a race.
