First, to walk 50 steps it takes you 32 seconds, that implies that it takes you
each step. Then the proportion we set up is 32/50.
Now, we use this proportion to calculate how long would it take you to walk 10000 steps, for that we simply multiply
So it would take you 6400 second to walk 10000 steps.
In a typical day to know how much time you spend walking you have to count every step you take anytime of the day that you find yourself walking, then you multiply the total number of steps with the proportion we set up above.
