Explanation:

Step1: Rewrite numbers in standard form

$8.166\times 10^{8}=816600000$ and $1.515\times 10^{9}=1515000000$

Step2: Calculate the difference

$1515000000 - 816600000=698400000$

Step3: Write result in scientific - notation

$698400000 = 6.984\times 10^{8}$

Answer:

$6.984\times 10^{8}$ kilometers
