Going the second circle

Meow! Thanks for the calculation!

When I come back, I want to fly to Kamchatka, eat some rainbow trout and check out the volcanoes.

How many miles will I get? I’ll have to fly for 9 hours, so this kind of sacrifice should be rewarded!

Your gut feeling was not lying! Muffin is planning yet another trip, but you got everything ready: you got the formula, and the condition for long-distance flights is taken into account.

Let’s add the mile calculation for the flight to Kamchatka.

To do this, we will have to repeat all the calculation steps for the first trip. The algorithm is the same, only the distance is different, and maybe the percentage. Let’s check!

As you can see, the result of our calculation isn’t a round number. There is no mistake, this is how JavaScript works. We will discuss why this happens in further courses. And we will round the numbers a little later.

// Copy the whole code below var percent = 0.25; var distance = 4125; if (distance > 10500) { percent = 0.35; } var miles = distance * percent; console.log('We’ll get ' + miles + ' miles for the flight to Irkutsk'); // Paste the code after this comment

What didn’t you like in this task?

Thanks! We’ll fix everything at once!
