Seema runs 5 miles more per week than her sister Padma. If Seema runs 17 miles per week, which equation could be used to find the number of miles Padma runs each week?

Since Seema runs 5 more miles than Padma, we could find how long Padma runs by subtracting 5 miles from the amount of miles that Seema runs. If P is equal to the distance that Padma runs, our equation is:

P = 17-5 = 12 miles.
