Mr Lee drive 31 miles from his house to Brookville and there is an extra information that is parkside is 4 miles south of springfield which is not required.

Given that  

Mr. Lee drove 8 miles from his house to park side .  

Parkside is 4 miles south of springfield.

From Parkside he drove 3 miles to springdale  

Then he drove 20 miles from springdale to brookville.

Need to determine how far Mr Lee drive in all, from his house to Brookville.

Also need to identify Extra or missing information.

Complete drive of Mr Lee from his house to Brookville is equal to 8 miles from his house to park side then 3 miles from Parkside to springdale , then 20 miles from springdale to brookville.

=> Complete drive of Mr Lee from his house to Brookville in miles = 8 + 3 + 20 = 31 miles

Hence Mr Lee drive 31 miles from his house to Brookville and there is an extra information that is parkside is 4 miles south of springfield which is not required.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
