Tres participantes en un concurso de TV están colocados en el centro
de un campo plano grande. A cada uno se le proporciona una regla
graduada de un metro, un compás, una calculadora, una pala
y (en diferente orden para cada concursante) los siguientes tres desplazamientos:
A: 72.4 m, 32.0° al este del norte
B: 57.3 m, 36.0° al sur del oeste
C: 17.8 m al sur
Los tres desplazamientos llevan al punto donde están enterradas las
llaves de un Porsche nuevo. Dos concursantes comienzan a medir de inmediato; sin embargo, el ganador calcula
primero a donde debe ir. Con tres cifras
significativas exprese la resultante.
