PSLE MAths Question 2005
A man went down a flight of stairs by walking a few steps and running 14 steps, taking a total of 41s. He repeated this by walking a few steps and running 6 steps, taking 65s to do so. What would be time taken if he only walked down the flight of stairs?
How hard is this?
What's your say?

Hey Sir Terence. THis is the bloody question where those P6 friends at my tuition centre asked their lot of seniors to try. Bloody difficult. I can't do it either.
