Compare Speeds

The table shows the top speeds, in miles per hour, of 5 luge athletes:

List the top speeds of the athletes in decreasing order.

The table shows the top speeds, in miles per hour, of 5 luge athletes:

Do any of the athletes have the same top speed rounded to the nearest tenth of a mile per hour? What about rounded to the nearest mile per hour?

The table shows the top speeds, in miles per hour, of 5 luge athletes:

There was a sixth athlete who was faster than the rider at 82.80 mph, but slower than the rider at 82.81 mph. What could the speeds of the 3 athletes be if all measured to the nearest thousandth of a mile per hour?
