Calculation of the Number of Pages in the Story

To find out how many pages the story contains, we need to determine the reading speed of Vasya and Petya and the time it took them to finish reading.

Given: - Vasya read 1 hour and 50 pages. - Petya read 60 pages. - Petya finished reading 10 minutes earlier than Vasya.

To calculate the number of pages in the story, we can use the following formula:

Number of pages = (Vasya's reading speed * Vasya's reading time) + (Petya's reading speed * Petya's reading time)

Let's calculate the number of pages in the story using the given information:

Vasya's reading speed = 1 hour 50 pages = 110 pages/hour Petya's reading speed = 60 pages/hour

Let's assume that both Vasya and Petya started reading at the same time and Petya finished 10 minutes earlier than Vasya. We need to convert the 10 minutes into hours to include it in the calculation.

10 minutes = 10/60 hours = 1/6 hours

Now, let's substitute the values into the formula:

Number of pages = (110 pages/hour * 1 hour) + (60 pages/hour * (1 hour - 1/6 hour))

Simplifying the equation:

Number of pages = 110 pages + 60 pages * (5/6)

Calculating:

Number of pages = 110 pages + 300 pages/6

Number of pages = 110 pages + 50 pages

Number of pages = 160 pages

Therefore, the story contains 160 pages.
