If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your a
Alja [10]

The number of pages the student can read in a minute is an illustration of rates.

The time left to complete the whole book is 90 minutes

From the complete question, the student's rate is:

\mathbf{Rate = 50\ pages/hr}

The number of pages is:

\mathbf{Total = 100\ pages}

First, we calculate the time to read the whole book

\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}

\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}

\mathbf{Total\ Time = 2\ hours}

The number of the student has read is:

\mathbf{Pages = 25}

Next, we calculate the time spent on the 25 pages

\mathbf{Time\ Spent = \frac{Pages}{Rate}}

\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}

\mathbf{Time\ Spent = 0.5\ hr}

Convert to minutes

\mathbf{Time\ Spent = 30\ minutes}

So, the time left is:

\mathbf{Time\ Left = Total\ Time - Time\ Spent}

This gives

\mathbf{Time\ Left = 2\ hours- 30\ minutes}

\mathbf{Time\ Left = 1\ hour, 30\ minutes}

Convert to minutes

\mathbf{Time\ Left = 90\ minutes}

Hence, the time left is 90 minutes
