I’m thinking of 5 numbers such that their mean is equal to their median. If 4 of the numbers are 14, 8, 16, and 14, what is the 5th number?

Please CW answers and hints in your responses.

I've just redesigned my experimental garden's shape. I couldn't stand all those keyholes and weird paths anymore.

Wrote a small article about it, which is like a long toot with more pictures, in case anyone is curious about it: arteteco.com/20shapes/

Interesting fact of the day: Diamonds are flammable

@njha I'm going to try this again but with a base mass for the ship itself in addition to the fuels weight. I'll play with different numbers to make sure it gives sane results but I think that should do the trick.


Ok so i made a mistake on this problem. Turns out this was accidentally a trick question. The answer is that any amount of fuel will get you to any height. The reason being that as the fuel is expended the mass of the ship approaches 0, so acceleration approaches infinity. So by the time the rocket is out of fuel it would be moving at the speed of light no matter how much fuel it started with.

As suck I will post a new version of this question and ill make sure i solve it BEFORE I post it.

== Math Problem of the Day ==

If you have a rocket traveling vertically with only the mass of its fuel to carry, with earth sea level gravity, then, how much fuel must you carry to reach a height of 1 kilometer if maintaining a newton of thrust uses up 1 gram of fuel per minute.

Bonus: show the equation with height and fuel per time are both unknowns (variables).
