4 Days.

The distance between the earth and the moon is 384,400 km.it takes 4 days for a spacecraft to travel from the earth to the moon.

Answer 2

The formula for calculating speed is speed =

$\frac{distance}{time}$

DISTANCE = 384400km = 384.4m

TIME = 4 DAYS = 345600sec

SPEED OF SPACECRAFT =

$\frac{384.4}{345600}$

= 0.00111226852 m/s
