Instructions

A vehicle needs 10 times the amount of fuel than the distance it travels. However, it must always carry a minimum of 100 fuel before setting off.

Create a function which calculates the amount of fuel it needs, given the distance.

Examples

calculateFuel(15) // 150
calculateFuel(23.5) // 235
calculateFuel(3) // 100

Notes

• Distance will be a number greater than zero.
• Return 100 if the calculated fuel turns out to be less than 100.

Solutions

function calculateFuel(n) {let ans = n * 10;return ans < 100? 100:ans;
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
