Anita is filling a small pool for her kids. Currently, there are 60 gallons of water in the pool and she is filling the pool at a rate of 50 gallons every 5 minutes. The pool holds 200 gallons of water.
Which equation represents the amount of minutes (m) that it will take to fill the pool?
O-10m + 200 = 60
-50m + 200 = 60
-10m + 140 = 60
-50m + 140 = 60
