E
and then when you get near to landing
.......................................…
............................... r -->
E is out of site maybe or has traveled around a couple times in the time we have traveled to Jupiter
..............................r -->J
so where E is when you land doesnt matter what matters is you travelled a straight line from earth to jupiter how far will that be

using this as a guide
jupiter is 778 million km
earth is 150 million km
so the shortest distance is 778 *10^6 - 150*10^6 = 628 *10^6
at 100 km/hour
t = distance/speed
t = 628*10^6/ 1*10^2
t = 628*10^6 *10^-2
t = 628*10^4 hours
t = 6.28*10^6 hours
this is 6.28 million hours to arrive at jupiter
8760 hours in a year
means it would take 716.9 years to arrive there
the earth would orbit the sun 716.9 times in the trip
and jupiter would orbit
716.9*(365/4332) = 60.4 orbits
thats a very very long trip
