How can I say to JS to increase a value everytime multiple conditions are met..without hardcoding it-CodePudding

I am trying to figure out this problem, basically my problem is: if the length (in seconds) is < 180 return 500(pences) . For every extra 60 seconds add 70 pences. So if for example I have 240seconds I should return 570pences if I have 300seconds i should return 640pences and so on. How can I achieve this result with JavaScript?

this is my code so far:

    function calculateTaxiFare(seconds) {
        if (seconds < 180) {
   return 500
      // I need something like this without hardcoding
}else if (seconds > 180 && seconds < 240) {
          return 575
}else if ( seconds > 240 && seconds < 300 ) {
          return 640
}
    }

console.log(calculateTaxiFare(245));

Thank you for your support.

CodePudding user response：

You need to integer divide the (length of time - 180 seconds) by 60 and add 1 (you can use Math.ceil for that operation) and then multiply that by 70 to get the additional fare:

function calculateTaxiFare(seconds) {
  return 500   Math.ceil((seconds - 180) / 60) * 70
}

console.log(calculateTaxiFare(245));
