I have a question that says Rachel runs 3.2 miles each weekday and 1.5 miles each day of the weekend how many miles will she have run in 6 weeks

The answer is very simple. Multiply 3.2 by 5 (5 is how many days is in the weekday part of a week) and your answer shall be 16. Now multiply 1.5 by 2 (2 is how many days is in the weekend part of a week) which is 3. Now add 16 and 3 which is 19 miles (and 19 miles is how many she would run in a week). Now all you have to do is multiply the total of miles by 6 (which is 114 miles). 114 miles is what you should have as your answer.

3.2 x 5 weekdays = 16

1.5 x 2 weekend days = 3

16+3=19

19 = 1 week

19x6=114 (6 weeks)
