#include <iostream>
using namespace std;
int main(){
double v0;
double v1;
double t;
double avg;
std::cout << "Enter v0, v1, and t: \n";
std::cin >> v0;
std::cin >> v1;
std::cin >> t;
avg = (v1 - v0) / t;
std::cout << "The average acceleration is " << avg; // Type ./29<29input.txt to send input text to here
