You walk up an escalator and count 60 steps. You decide to go down that
same escalator, against its upwards motion, and this time you count 90
steps. If the escalator were to be stopped, how many steps would you
count then? your asnwer is...
72 steps!
It took me like an hour to figure it out but I got it!
Hope this helps!
