Escalator Step Math Problem

Here s our discussion of the version of the of the problem in chapter 7 of the aops s introduction to algebra.

Escalator step math problem.

The man has walked up 28 steps so the red step is 28 steps behind him. Sohan started simultaneously from the bottom taking 2 steps to every 1 step taken by rohan. I run up the escalator at a constant speed in the direction of the stairs and write down the number of steps a we climbed. If a 24 and b 264 how many steps are visible at any one time on the escalator.

Problem 6 rohan walked down a descending escalator and took 40 steps to reach the bottom. Frank walked up the escalator at a speed of 2 steps every second. In my approach a is the velocity the unit of distance is the step and the unit of time is the time it takes bob to reach the top. In this section we will learn how to solve escalator problems in the topic time distance and speed.

If the escalator shows 10 steps and goes down in this problem it shows 15 steps and goes down solving for n would give 10 and only the velocity would be negative. Frank and ronnie embarked on a moving escalator to the second floor of a shopping mall. Escalator problems in time distance and speed examples. Then we turn around and run it at the same constant speed in the opposite direction and write down the number of steps b that i climbed.

We then drew a diagram of the situation just as the man reaches the top. This is a great problem. Today he had some difficulty with a problem about an escalator. And i ll end with a bit of nit picking.

Time taken by rohan to reach the bottom from the top is the same as time taken by sohan to reach the top from the bottom.
