Question

Calcular la velocidad media de un carro que recorrio 390 kilometros en 150 kilometros por hora. a) expresa el resultado en km/h b)expresa el resultado en m/s porfa es urgente

Answer 1

Answer:

a) v = 150 km/h

b) v = 41.66 m/s

Explanation:

a) The average velocity in km/h is given by the statement in the exercise:

$v=150\frac{km}{h}$

b) To calculate the average velocity in m/s you need a to do the following conversion:

$v=\frac{150km}{h}*\frac{1000m}{1km}*\frac{1h}{3600s}=41.66\frac{m}{s}$

hence, you have that the average velocity of the car is 150km/h = 41.66 m/s
