Luke jogged a total of 56.5 miles last week.  If Luke jogged the same distance, d, each day for 3 days and half that distance on each of the remaining days, write an algebraic equation that can be used to determine how many miles he jogged each day.    


Sagot :

Well, you get 2n miles for each of the first 3 days and n miles for each of the other 4. That is, 2n+2n+2n+n+n+n+n=56.5. That is, 10n=56.5 or n=5.65 miles each of the last 4 days. The first 3 days, Luke jogged double that, that is, 11.3 miles each day.
