Sally and joan have been competing to see who can get more steps in each week on their pedometers. during the past week sally has done 65,723 steps and joan has done 90,345. sally is getting tired of losing and so she says that she actually walks more if you look at actual distance. her stride length length is 5.5 inches longer than joans 18 inch stride. if sally walks 70,000 steps next week, how many more steps than sally does joan have to do to make sure she walks furthest distance next week.
