Respuesta: " ¿Quién diría que una persona que no haya culminado sus estudios universitarios pudiera hablar más de diez idiomas, y además crear un idioma universal? "
We have:
in hungarian:
h = 150 words / min
in polish:
190 words / min
Let:
x: number of words in Hungarian.
y: number of words in Polish.
We have the following system of equations:
(1/150) * (x) + (1/190) * (y) = 5 y = x + 270
The solution is:
x = 300 words
y = 570 words
Therefore the time speaking in each language is:
in hungarian:
(1/150) * (300) = 2 min
in polish:
(1/190) * (570) = 3 min
Answer: in hungarian: 2 min in polish: 3 min
