lisa is increasing her running distance at a rate of 12% per week. if she begins by running 2 miles, how long until her running distance is 5

I think( so correct me if i'm wrong)Using the distance formula... D=Rate x Time, you alter it so that it equals time, since you want to find the number of weeks.
Time = Distance/ rate
SInce you start off at 2 and end up with 5, the total distance is 3 (I subtracted 5-2). And rate is already 12% (this is the iffy part, I'm not sure if you change the 12%  in anyway but lets move on)

SO Time= 3miles/ 12% which is 1/4 of a week, or possibly

Time = 3 miles/ 0.12 which would equal 25 weeks
Do they give you these answers?

The answer would be option 4
