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

The Frosty Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On a hot summer day, the shop sold 8 more sundaes than

sineoko [7]

Answer:

The number of sundaes sold are 36.

Step-by-step explanation:

The cost of each sundae is $2 and the cost of each banana splits is $3.

The number of sundae sold be "x" and banana split be "y".

Thus, the total amount spent is,

= $2x+3y$

The total amount spent is given to be $156. Thus,

156 = $2x+3y$

It is also given that, the shop sold 8 more sundaes than banana splits. In equation form,

$x = y+8$

$y = x-8$ ,

Inserting this value of y in above equation, we get,

156 = $2x+3(x-8)$ = $5x-24$

$180 = 5x$

Thus, x = 36 = number of sundae sold.
