Answer:
17.6
(18 rounded to the nearest 10th)
Explanation:
The keyword is than, which means you are subtracting Saturn to Jupiter.
29.5 -11.9 = 17.6
You can fact check you answer by adding the lowest number to your answer.
11.9+17.6=29.5
Which means, Saturn takes 17.6 more years to orbit the sun than Jupiter.
