Answer

Explicación:

Paso 1: Calcular la distancia promedio del coche sin peso

Sumamos las distancias de los tres ensayos: $75 + 72+73 = 220$ cm. Luego dividimos por el número de ensayos (3): $\frac{220}{3}\approx73.33$ cm.

Paso 2: Calcular la distancia promedio del coche con peso

Sumamos las distancias de los tres ensayos: $61 + 52+55 = 168$ cm. Luego dividimos por el número de ensayos (3): $\frac{168}{3}=56$ cm.

Paso 3: Resolver la pregunta sobre si el coche más pesado viajó más lejos

Observando los promedios, vemos que el coche sin peso viajó más lejos que el coche con peso, entonces la respuesta es NO.

Paso 4: Resolver la pregunta sobre cómo afectó la altura de la rampa la distancia recorrida

Observando los datos del Lab #2, vemos que a medida que aumenta la altura de la rampa (de 1 libro a 2 libros y luego a 4 libros), la distancia recorrida por el coche aumenta (de 9 cm a 27 cm y luego a 54 cm). Entonces, la altura de la rampa afecta positivamente la distancia que el coche rueda.

Respuesta:

¿Cuál fue la distancia promedio recorrida por el coche (en cm)? Respuesta: $\approx73.33$ cm ¿Cuál fue la distancia promedio recorrida por el coche con peso? Respuesta: 56 cm ¿El coche más pesado viajó más lejos? Respuesta: NO ¿Cómo afectó la altura de la rampa la distancia que el coche rueda? Respuesta: A medida que aumenta la altura de la rampa, la distancia recorrida por el coche aumenta.
