Question
If you travel at 400000km/hr how long will it take you to get to Uranus

Answer
How old are you Lana?
Let me guess!
'quite young' should be correct.
If you just type "distance to uranus" in google or yahoo, you will get the distance between earth and uranus on the web.

Knowing the speed of light 1,86000 miles / sec (approx) or 300,000 km/sec, then
400000 km/3600 sec = 111.111 km/sec !
time of travel (sec) = distance in km/ 111.111!

I could have "spoon fed" you the answer, but i respect people and am sure you will get the answer "yourself" with this slight friendly help from me!

[however have you given a thought to the fact that even as you begin your journey, uranus itself will move in it's orbit around the sun! So the "real" answer would be something quite quite complicated. especially as you will be moving along a curve followed by interceptor missiles in their flight path behind enemy planes!
Think about that. Use a paper and pencil to understand what would happen and how.]
