To find the number of miles Lisa will ride each week, we need to determine how many miles she rides in one hour and then multiply it by the number of hours she rides each week.
Lisa rode 15 miles in 90 minutes, which is equal to 1.5 hours (since 60 minutes = 1 hour).
Therefore, Lisa rides 15 miles / 1.5 hours = <<15/1.5=10>>10 miles every hour.
If Lisa's goal is to ride 8 hours every week, then she will ride 10 miles/hour * 8 hours = 80 miles each week.
Therefore, the correct answer is 80 miles.
