Two brothers A and B run "one kilometer". However, person A says:
You need to add 100 to any number B says to get the real answer!
Person B says:
You need to multiply any number A says by 6/5 to get the real answer!
How many meters did A run? How many meters did B run?
Mathematical notation:
\[A_{false}(x)=x\]
\[B_{false}(x)=x\]
\[A_{true}(x)=x\cdot B_{true}(\frac{6}{5})\]
\[B_{true}(x)=x+A_{true}(100)\]
\[Find\:A_{true}(1000)\;and\;B_{true}(1000)\]
