Detective Miles is investigating a peculiar case involving three antique dealers, A, B, and C, suspected of fencing stolen goods. Each dealer made a statement about the number of stolen artifacts they possessed, describing hypothetical transfers: - Dealer A claimed: 'If I had one more artifact, I'd have twice as many as Dealer B.' - Dealer B claimed: 'If Dealer C gave me three artifacts, we'd both have the same number.' - Dealer C claimed: 'If Dealer B gave me five artifacts, I would have one more than Dealer A.' Assuming all dealers are telling the truth about these hypothetical scenarios, what is the exact difference between the number of artifacts Dealer A possesses and the number Dealer C possesses (A - C)?

Solution
4 — Let 'a', 'b', and 'c' represent the current number of artifacts for Dealer A, B, and C respectively.
We translate each statement into an algebraic equation:
1. **Dealer A's statement:** 'If I had one more artifact, I'd have twice as many as Dealer B.'
Equation 1: a + 1 = 2b
2. **Dealer B's statement:** 'If Dealer C gave me three artifacts, we'd both have the same number.'
This means Dealer B would gain 3 (b+3) and Dealer C would lose 3 (c-3).
So, b + 3 = c - 3
Equation 2: b + 6 = c
3. **Dealer C's statement:** 'If Dealer B gave me five artifacts, I would have one more than Dealer A.'
This means Dealer C would gain 5 (c+5) and Dealer A would have 1 more than their current amount (a+1).
So, c + 5 = a + 1
Equation 3: c + 5 = a + 1
Now we solve the system of equations:
* From Equation 1, we can express 'a' in terms of 'b':
a = 2b - 1
* From Equation 2, we have 'c' in terms of 'b':
c = b + 6
* Substitute these expressions for 'a' and 'c' into Equation 3:
(b + 6) + 5 = (2b - 1) + 1
b + 11 = 2b
* Solve for 'b':
11 = 2b - b
b = 11
* Now find 'a' and 'c' using the value of 'b':
a = 2b - 1 = 2(11) - 1 = 22 - 1 = 21
c = b + 6 = 11 + 6 = 17
Finally, calculate the difference between the number of artifacts Dealer A possesses and Dealer C possesses (A - C):
A - C = 21 - 17 = 4
The correct answer is 4.

An interstellar probe is traveling directly away from Earth at a constant speed of 50 km/s. It is currently 1.5 billion kilometers from Earth. At this exact moment, it transmits a crucial data packet back towards Earth. Assuming the data signal travels at the speed of light (approximately 300,000 km/s), how far away from Earth will the probe be *at the exact instant* Earth receives the data packet?

An astronaut lands on a newly discovered asteroid, which is entirely enveloped in a strange, thick, swirling 'fog'. This 'fog' is intensely bio-luminescent, emitting so much light that it causes complete optical whiteout (visibility zero). Despite being unable to see anything, the astronaut expertly navigates to precise mining coordinates, extracts a rare mineral, and returns to their ship without incident. How did the astronaut accomplish this feat?
