1. 这里应该用double存精度而不是int
2. km没有必要 \times 1000
3. 建议使用变量来存贮 bike walk

#include<bits/stdc++.h>
using namespace std;
double bike=50.0,walk=0.0;
int main()
{

    double km;
    cin>>km;

    walk=km/1.2;
    bike=km/3.0+50.0;

    if(walk>bike)
        cout<<"Bike";
    else if(bike>walk)
        cout<<"Walk";
    else
        cout<<"All";
    return 0;
}
