Question

С какой скоростью оператор набирает текст на компьютере если за 2ч 25мин он набрал 820 строчек текста

Answer 1

2ч 25мин=145мин.
820:145 = 5,655(строч./мин)≈6(строч/мин)

Answer 2

820:145=5.6(ст.т) за минуту

Answer 3

Calculating Typing Speed

To calculate the typing speed of the operator, we can use the formula:

Typing Speed = Total Characters Typed / (Time Taken in Minutes / 60)

First, let's calculate the total characters typed. We'll assume an average of 5 characters per word for this calculation.

Given: - Total time taken = 2 hours 25 minutes = 145 minutes - Total number of lines typed = 820

We can use the average number of characters per line to calculate the total characters typed.

Calculation

Let's calculate the total characters typed: - Assuming an average of 5 characters per word, we can estimate an average of 50 characters per line (including spaces and punctuation).

Total characters typed = 820 lines * 50 characters per line

Now, we can calculate the typing speed using the formula mentioned above.

Typing Speed Calculation

Typing Speed = Total Characters Typed / (Time Taken in Minutes / 60)

Typing Speed = (820 * 50) / (145 / 60)

Typing Speed = 41,000 / 2.42

Typing Speed ≈ 16,942 characters per hour

So, the operator's typing speed is approximately 16,942 characters per hour.
