The distance from the earth to the moon is approximately 240,000 miles. if a rocket travels at a speed of 7.50 km/sec, it will take days to travel between the earth and moon.

In a simplistic way, 
time = distance/velocity.

This is a simple formula which is valid only average velocity is computed for the travel between the earth and the moon.

Note that
1 mile = 1.60934 km

Therefore
d = 240,000 mi = 240,000*1.60934 = 386,241.6 km

The time of travel is
(386241.6 km)/(7.5 km/s)
= 51,499.9 s
= (51499.9)/(3600) = 14.305 h
= 14.305/24 = 0.596 days
