always use significant figure rules. remember that these rules apply to all numbers that are measurements. city b is north of city a, and the 400 mile trip by car takes 8 hours. the cities are 320 miles apart in a straight line. what is the velocity of a trip from city a to city b? mph 40 50 10
Answer
Explanation:
Step1: Recuerda la fórmula de velocidad
La velocidad $v$ se define como $v=\frac{d}{t}$, donde $d$ es el desplazamiento (distancia en línea recta) y $t$ es el tiempo.
Step2: Identifica los valores de $d$ y $t$
El desplazamiento $d = 320$ millas y el tiempo $t=8$ horas.
Step3: Calcula la velocidad
$v=\frac{320}{8}=40$ mph
Answer:
40 mph
