Lisa runs five days a week she runs 7.9 miles each day. How many miles does she run each week?
To find how many miles Lisa runs each week, we need to multiply the number of miles she runs each day by the number of days she runs per week.
Her daily mileage = 7.9 miles/day
Number of days she runs per week = 5 days/week
Therefore, the total number of miles she runs each week is 7.9 miles/day * 5 days/week = <<7.9*5=39.5>>39.5 miles/week.
Therefore, Lisa runs 39.5 miles each week.
