always use significant figure rules. remember that these rules apply to all numbers that are measurements. a car travels from city a to city b to the east. it takes 2 hours, and the road mileage is 100 miles. the map shows that the cities are only 80 miles apart (straight - line distance). calculate the average velocity. mph 40 50 10

Answer

Explanation:

Step1: Definir fórmula de velocidad promedio

La velocidad promedio $v$ se define como $v=\frac{\Delta x}{\Delta t}$, donde $\Delta x$ es el desplazamiento y $\Delta t$ es el tiempo transcurrido.

Step2: Identificar valores

El desplazamiento $\Delta x = 80$ millas (distancia recta entre ciudades) y $\Delta t=2$ horas.

Step3: Calcular velocidad promedio

$v=\frac{80}{2}=40$ mph

Answer:

40
