Answer:

It would take 106 minutes rounded to the nearest minute to read 76 pages.

Explanation:

The ration of time to pages is: #25:18# which is the same as #25/18#

We need to how many minutes, let's call it #m#, it takes to read #76# pages so we can write:

#25/18 = m/76#

Solving for #m# gives:

#76 * 25/18 = 76 * m/76#

#1900/18 = cancel(76) * m/cancel(76)#

#m = 105.6#
