//"sakura".length = ???

//speed more 0 ??

// my answer is two string...

nice , what is the colon for ?

That's too vague, please detail what are you suggesting.

this kata need more information about code and requirements

Yeeeeeeeeeey!!
This was the last level 8 problem in C++.

P.S. I'll leave a comment as a reminder. ;)

Dividing the speed by 5 should be a valid answer too (instead of multiplying the distance by 5).
The tests shouldn't rely on a rounded value to 15 decimal spots.

Damn, the story makes my stomach pain.
That's really upset.

This kata is so bad, it has nothing to do with anything.

what is the inf ?

fixed

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end

I started to learn JavaScript 5 weeks ago and I try to understand step by step. I should create a constant with a fix value (400), but I want to use "ratio", so I used " / " sign in two variablem. If I use only one " / " with the speed, there is no problem with the decimals.

what language?
