Question

Помогите умоляю! Мотоциклист проехал 250 км. Из них 26% он проехал за первый час движения. Сколько км мотоциклисту осталось проехать? И еще одно: Света прочитали 63 страницы, что составляет 9/11 всей книги. Сколько страниц в книге? Заранее спасибо!

Answer 1

Calculation of Remaining Distance for the Motorcyclist

To calculate the remaining distance for the motorcyclist, we need to determine the distance covered in the first hour and subtract it from the total distance of 250 km.

Given that the motorcyclist covered 26% of the total distance in the first hour, we can calculate the distance covered in the first hour as follows:

Distance covered in the first hour = (26/100) * 250 km

Let's calculate it:

Distance covered in the first hour = (26/100) * 250 km = 65 km

Now, to find the remaining distance, we subtract the distance covered in the first hour from the total distance:

Remaining distance = Total distance - Distance covered in the first hour

Remaining distance = 250 km - 65 km = 185 km

Therefore, the motorcyclist has 185 km left to travel.

Calculation of Total Number of Pages in the Book

To calculate the total number of pages in the book, we need to determine the number of pages represented by the fraction 9/11 and then find the total number of pages.

Given that 63 pages represent 9/11 of the entire book, we can calculate the total number of pages in the book as follows:

Total number of pages = (63 pages * 11) / 9

Let's calculate it:

Total number of pages = (63 pages * 11) / 9 = 77 pages

Therefore, the book has 77 pages in total.

I hope this helps! Let me know if you have any further questions.
