1. Calcular la distancia total recorrida:
- De A a B: 460 m
- De B a C: d = 3 \, \text{m/s} \times 38 \, \text{s} = 114 \, \text{m}
- Distancia total, d_{\text{total}} = 460 \, \text{m} + 114 \, \text{m} = 574 \, \text{m}

2. Calcular el tiempo total empleado:
- Tiempo de A a B: t_{AB} = 3 \, \text{min} = 180 \, \text{s}
- Tiempo de B a C: t_{BC} = 38 \, \text{s}
- Tiempo total, t_{\text{total}} = 180 \, \text{s} + 38 \, \text{s} = 218 \, \text{s}

3. Calcular rapidez media:
- \text{Rapidez media} = \frac{d_{\text{total}}}{t_{\text{total}}} = \frac{574 \, \text{m}}{218 \, \text{s}} \approx 2.63 \, \text{m/s}

4. Calcular desplazamiento total (distancia recta de A a C, considerando el Este como la dirección):
- El desplazamiento total en línea recta es la misma distancia, ya que toda la trayectoria es hacia el Este.
- Desplazamiento total, d = 574 \, \text{m}

5. Calcular velocidad media:
- \text{Velocidad media} = \frac{d}{t_{\text{total}}} = \frac{574 \, \text{m}}{218 \, \text{s}} \approx 2.63 \, \text{m/s}
