Question

13) Zach can read 7 pages of a book in 5 minutes. At this rate, how long will it take him to read the entire 175 page book?  (Convert your final answer to hours and minutes)

Answer 1

Setting a proportion ;

$\frac{Pages} {Minutes}$

Let the time take to read 175 pages be $x$

$=\frac{7}{5}=\frac{175}{x}$

Cross multiplying ;

$175×5=7×x$

$7x =875$

$x$ =125 minutes.

Converting the time into hours and minutes

1 hour =60 minutes

? =125 minutes

=2 hours 5 minutes
