Problem
At a given time, Saturn was \( 9.1 \times 10^{8} \) miles from the Sun and Earth was \( 9.3 \times 10^{7} \) miles from the Sun. By what distance is one planet closer to the Sun than the other planet? A \( 2 \times 10^{1} \) B \( 2 \times 10^{15} \) C \( 8.17 \times 10^{7} \) D \( 8.17 \times 10^{8} \)
Solution
Step 1 ：\(d = |(9.1 \times 10^{8}) - (9.3 \times 10^{7})|\)
Step 2 ：\(d = |9.1 \times 10^{8} - 0.93 \times 10^{8}|\)
Step 3 ：\(d = 8.17 \times 10^{8}\)
