Final answer:
To find out how much farther Uranus is from the Earth than Saturn, subtract the distance between Saturn and Earth from the distance between Uranus and Earth. Uranus is 167*10^7 km farther from Earth than Saturn.
Step-by-step explanation:
To find out how much farther Uranus is from Earth than Saturn, we need to subtract the distance between Saturn and Earth from the distance between Uranus and Earth. The distance from Earth to Uranus is given as 287*10^7 km, and the distance from Earth to Saturn is given as 12*10^8 km.
So, the difference in distance is 287*10^7 km - 12*10^8 km = 287*10^7 km - 120*10^7 km = 167*10^7 km.
Therefore, Uranus is 167*10^7 km farther from Earth than Saturn.
