Un avioncito de control remoto viaja con una velocidad constante de 20 km/hr el tiempo en que se realiza el vuelo es de 25 minut
rosijanka [135]

Answer:

Distancia = 27559.06 pies

Explanation:

Dados los siguientes datos;

Velocidad = 20 km/hr

Tiempo = 25 minutos

Conversión de minutos a horas;

60 minutos = 1 hora

25 minutos = 0.42 horas

Para encontrar la distancia;

Distancia = velocidad * tiempo

Distancia = 20 * 0.42

Distancia = 8.4 km

Conversión de kilómetros a pies;

1 km = 3280.84 pies

8.4 kilometros = 8.4 * 3280,84 = 27559,06

Distancia = 27559.06 pies
