Question

Hallar la velocidad de una nave espacial que recorre 6,400km en 15minutos
a)km/hr
b)m/seg​

Answer 1

Respuesta:

a) v =  25,600km/h   ;     b) v = 7.11 m/seg.

Explicación:

a)

d = 6,400km

t = 15mín =  15 * 1/60 h = 0.25 h

v = d / t

v = 6,400km / 0.25 h = 25,600km/h

v =  25,600km/h

b)

d = 6,400km = 6,400* 1000m = 6,400,000m

t= 15mín = 15* 60seg. = 900seg.

v = d / t

v = 6,400,000m / 900seg.

v = 7.11 m/seg.
