About 62 then?

No. I can't tell you any more than that, you must solve it yourself.

I get about 60.6326 (I hate decimals so I won't push it past four digits) miles, though that number can vary wildly on a variety of factors, such as wind speed, ocean currents, the strength and armor of the warship and the accuracy and power of the missile (for all we know it might not destroy the ship), and whether there are other forces at work (something might interfere with the missile or sink the ship before the missile's arrival).

Spar is absolutely correct! I got 60.632686 miles, which is identical to Spar's. Now, the other factors like wind speed, currents, and armor are ignored in this math problem. There. The third problem comes tomorrow.

Oh, I know! How about some physics?

An astronaut on the Moon test fires a small railgun. It fires a projectile horizontally at 6 miles per second. How far does the projectile travel?

Naturally, this is the Moon, so ignore air resistance. But factor in the Moon's weaker gravity, and the Moon's curvature. The little projectile travels far...

Too many variables. You aren't giving a height or location the projectile is launched from (the Moon has a varying gravitational pull thanks to it peculiar shape), direction of travel, mass of said object, or other vital information. The resultant distance ranges anywhere, including escaping the Moon's gravity or smashing into a mountain on the other side of the Moon.

Aw shit. Umm, I'll try to make up a new one then.

That's why I didn't even attempt this one...

I'd suggest using straight number problems rather than relying on realistic examples. Reality has a tendency to be unpredictable, thus is hard to calculate a distinct answer.

extremely agreed. but seriously im a nerd in class so i think we should have more quizzes like this.
