Kane is training for a marathon. He starts by running 3 miles during every train session. Each week plans to increase the distance of his run by 1/4 mile.
Since a marathon is 26 miles that means that we would get 26=1/4x+3 so we would subtract 3 from both sides so you would get 23=1/4x then we would multiply 4 from both sides and we would get that it would take him 92 weeks to get to a marathon
