# Need some guidance

You need to plan a road trip. You are traveling at an average speed of 40 miles an hour. Given a distance in miles as input (the code to take input is already present), output to the console the time it will take you to cover it in minutes. Sample Input: 150 Sample Output: 225

Darryl T. Davis Your answer lies in the following formula which you might have seen in a physics class:
distance = speed × time
So, using this formula, you can write some JS code
An implementation for you:
const SPEED = 60 //mph
const distance = Number(prompt('Enter distance in miles: '))
const timeInMinutes = (distance / SPEED) × 60 //convert hours into minutes
console.log(time)
I am actually using ES6 syntax here, so that's why I have used the const keyword. And semicolon is not at all necessary (pointing out Alphin K Sajan 's mistake here)
Enjoy!!
PS. you can replace prompt() with readline()

Darryl T. Davis There are some syntactical errors in your code like missing of semicolon at end of stmts and Remember you are writing a general program therefore dont use the values in Example given ...
Try this :
var distance = parseInt(readLine(), 10);
distance=distance/40*60;
console.log(distance);

function main() {
var distance = parseInt(readLine(), 10);
//your code goes here
var distance = 150/40
var time = (3.75 * 60) == 225
console.log(time)

Questions 3
// Passes all tests
function main() {
var amount = parseFloat(readLine(), 10);
var rate = parseFloat(readLine(), 10);
function convert(amout,rate){
var final=amout*rate;
return final;
}
console.log(convert(amount, rate));
}

Explanation: It will take 150/40 = 3.75 hours to cover the distance, which is equivalent to 3.75*60 = 225 minutes.

Darryl T. Davis Explanation : It will take 150/40 = 3.75 hours to cover the distance, which is equivalent to 3.75*60 = 225 minutes.
Hint : 1.First take user input (distance)
2. Convert distance to time in minutes
3. Output distance to screen ...
For help with codes , Post your attempt first ....

function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
var sum = 0;
var count = 0;
for (i=1;i<depth;i++)
{
sum=sum+7;
count++;
if (sum>=depth)
{
break;
}
else
{
sum=sum-2;
}
}
console.log(count);
}

Darryl, very good explanations but unfortunately, the console log still not accepting the result. Thank you for the great detail explanations, anyway.
