Calculation of the Number of Steps for Cheburashka on a Stationary Escalator

To calculate the number of steps Cheburashka would count while descending on a stationary escalator, we need to consider the information provided in the question.

According to the question, Cheburashka and Gena counted 60 and 90 steps, respectively, while descending on a moving escalator. Additionally, it is mentioned that Cheburashka descended three times slower than Gena.

Let's assume that Gena's speed is represented by "x" steps per unit of time. Since Cheburashka descends three times slower, his speed can be represented as "x/3" steps per unit of time.

To find the number of steps Cheburashka would count on a stationary escalator, we need to determine the time it takes for Gena to descend the 90 steps on the moving escalator. We can then use this time to calculate the number of steps Cheburashka would count at his slower speed.

Unfortunately, the search results provided by You.com do not contain the necessary information to directly answer this question. However, we can still proceed with the calculation based on the information given.

Let's assume that Gena takes "t" units of time to descend the 90 steps on the moving escalator. In the same amount of time, Cheburashka would only be able to descend (x/3) * t steps on the stationary escalator.

Since we know that Gena counted 90 steps on the moving escalator, we can set up the following equation:

(x/3) * t = 90

To find the value of "t," we can rearrange the equation:

t = (90 * 3) / x

Now, we can substitute the value of "t" into the equation to find the number of steps Cheburashka would count on the stationary escalator:

(x/3) * [(90 * 3) / x] = 90

Simplifying the equation:

90 = 90

This equation shows that the number of steps Cheburashka would count on a stationary escalator is equal to 90, which is the same as the number of steps Gena counted on the moving escalator.

Therefore, Cheburashka would count 90 steps on a stationary escalator.
