Question

un coche viaja com MRU a la velocidad de 54 km/h durante 12 s. halle la distancia que recorrio

Answer 1

E= V,T

$12seg (\frac{1 hora}{3600seg} ) = \frac{12}{3600} = \frac{6}{1800} = \frac{3}{900} = \frac{1}{300} hora$

$E= (54)\frac{1}{300} = \frac{54}{300} = \frac{9}{50} = 0,18 km = 180 m$

Listo

E =
