Explanation:

Step1: Identify given distances

Saturn's distance from sun is $1.4\times10^{9}$ km, Venus's is $1.1\times 10^{8}$ km.

Step2: Make exponents the same

Rewrite $1.4\times10^{9}$ as $14\times10^{8}$.

Step3: Subtract the distances

$(14\times10^{8})-(1.1\times10^{8})=(14 - 1.1)\times10^{8}=12.9\times10^{8}$.

Step4: Convert to proper scientific - notation

$12.9\times10^{8}=1.29\times10^{9}$ km.

Answer:

$1.29\times10^{9}$
