Help me in solving FIT problem

My issue

Can you explain the constraints of this questions?

My code

#include <stdio.h>

int main(void){
    int x;
    scanf("%d",&x);
    printf("%d",2*x*5);
    
    

	// your code goes here
	return 0;
}

your logic is right but u have to put your code inside test case loop like this

#include <stdio.h>

int main(void) {
	// your code goes here
	int T,X,i,distance;
	scanf("%d",&T);
	for(i=0; i<T; i++){
	    scanf("%d",&X);
	        distance=10*X;
	        printf("%d\n",distance);
	
	    }
}
