"Trip Planner" in JS isn't accepting my code, can anyone help?

Question

"Trip Planner" in JS isn't accepting my code.
Here is my code =>

function main() {
var distance = parseInt(readline(), 10);
var speed = 40;
var time = distance/speed;
var ans = time*60;
console.log(ans);
return;
}

main()

Answer 1

L should be uppercase in readLine()
No need to call main() since it's done by compiler itself

function main() {
var distance = parseInt(readLine(), 10);
var speed = 40;
var time = distance/speed;
var ans = time*60;
console.log(ans);
// return;
}

//main()
