Shana ran 6miles in 1 week. this is one third of what she ran in the month. let m represent the number of miles shana ran in a l
Slav-nsk [51]
Let m be the distance (in miles) she runs in a month
and w be the distance (in miles) she runs in a week

since the total distance she run in a week is one third of what she run in a month, in equation form
w = m/3

to calculate the distance she run  in a month,
m = 3w
m = 3(6 miles)
m = 18 miles in a month
