Problema Solution
A tourist is one-third of the way up a flight of stairs. If she climbs 11 more steps, she will be
half way up. The number of steps in the flight is ___________. Show your solution.
Answer provided by our tutors
let 'x' represent half the number of steps, then '2(x-11)' represents all of the steps
11 steps short of halfway, the tourist has climbed 1/3 of the steps:
(x-11) = 2x/3
solving for 'x' we have x=33
the total number of stairs is 2*33 = 66
