if d=10000000000.0 km, t=10000000000.0 s, what is the delta?

I can modify it as:
if d=10000000000.0 km, t=10000000000.000000 s, what is the delta?

And I still recommend Enlighten or Yush to answer these 2 questions.

let's start with some simple ones - Enlighten (344 bytes) 2008-01-11, 09:49:10 (197271)
- 2.7km/s = 2.7m/ms, is this correct? (无内容) - squirrel (0 bytes) 2008-01-11, 10:41:31 (197290)
  - i think so. if you think of it as 8x10^3 m / 3x10^3 ms. (无内容) - Enlighten (0 bytes) 2008-01-11, 10:49:51 (197295)
    - 2.7km/s = 2.7m/ms = 0.0027km/ms - squirrel (143 bytes) 2008-01-11, 10:56:33 (197299)
      - i'm not sure. but i think you can't say - Enlighten (217 bytes) 2008-01-11, 11:04:17 (197302)
        
        ok, i think the problem arises when you use m and ms. - Enlighten (184 bytes) 2008-01-11, 11:07:13 (197303)
        
        You gave "3.0000000s", not 3s. - squirrel (79 bytes) 2008-01-11, 11:09:48 (197307)
