Answer 2

Given,

Zach can read 7 pages of a book in 5 minutes.

To Find,

The time taken to read the entire book (175 pages).

Solution,

Pages Zach can read in 5 minutes = 7

Total number of pages in the book = 175

Therefore, taking the total number of pages as sets of 7, we can divide the total no. of pages by 7.

$\dfrac{175}{7}$

= 25

Therefore Zach has 25 sets of 7 pages each. Multiplying this number with the time taken, we can write it down as,

25 x 5 = 125 minutes.

Therefore,

Zach takes 125 minutes to complete the book.

1 hour = 60 minutes

So, in order to convert the minutes to hours,

$\dfrac{125}{60}$

= 2 hours 5 minutes.

So,

Time taken in minutes = 125 minutes.

Time taken in hours = 2 hours 5 minutes.
