Answer:
It depends on the location of the Earth and Saturn. Depending on whether the earth is between sun and saturn, or sun is between earth and saturn, the distance from earth to saturn varies. Obviously, if the earth is between the Sun and Saturn, the shortest distance will be. We will understand that the gap between Earth and Saturn is:
Step-by-step explanation:
s = 1 275 000 000 km
The time required to travel that distance is:
t = s/v = 45535 hours or 1897.3 days
