Solution

The correct options are
A 1.41919x1012 m
C 1419190000000 m
D 1.41919x $10^{9}$ km
The total distance travelled by the spaceship between Earth and Saturn = Distance between (Earth & Mars + Mars & Saturn)
$= 2.2253 \times 10^{8} k m + 1.19666 \times 10^{9} k m = 2.2253 \times 10^{8} k m + 11.9666 \times 10^{8} k m = 14.1919 \times 10^{8} k m = 1.41919 \times 10^{9} k m = 1.41919 \times 10^{12} m = 1419190000000 m$
