There’s 5 weekdays in a week so 3.2 x 5 = 16 so 16 is how many miles she runs for every weekday for one week since it’s asking 6 weeks multiply 6 x 16 = 96 so 96 is how many miles she ran in 6 weeks for every weekday now you need the weekends there’s 2 days on the weekend so 1.5 x 2 = 3 so 3 is how many miles she runs on the weekend for one week now multiply 3 x 6 = 18 so 18 is how many miles she runs every weekend for 6 weeks now you add it all together so 96 + 18 = 114 so Rachel runs 114 miles in a span of six weeks
