Calling all maths genius for help........to solve the following qns:-
Tried to solve but then apparently my maths had returned a huge bulk to my former teachers.
There were 2 identical flight of steps. For the 1st flight of steps, Jim walked up some steps and ran 7 steps in 70s. For the 2nd flight of steps, he walked up some steps and ran 15 steps in 46s. How long did Jim take to walk up both flight of steps? (Ans: 182s).
