1) The smallest 3 digit prime number is 101. The biggest 4 digit prime number is 9973. And the sum of those numbers is 10074.
2) Anna walked \(8762-80^2=8762-6400=2362\left(m\right)\) more than Becky. (Those mad girls walking such long distances for no reason)
3) The biggest number among them is C)8977
