When I walk up an escalator in 7 steps, it takes me 30 seconds to reach the top.
If I run up the same escalator in 13 steps, it takes me 21 seconds.
How much time will it take for me to reach the top if I do not move up any steps on the escalator?

answer is = 40.5
The 6 additional steps took 9 seconds
, thats 1.5 seconds per step .
thus it will take 7*1.5 + 30 seconds = 40.5 seconds
