Answer:
let m be minutes, p be pages
pages read = times(in minutes) * reading speed(pages per minutes)
p=m*(60/20)
p=3m
For every increase of a minute of reading time, pages that Wesly have read will increase by 3

Remember the a² in formula has nothing to do with the a we have to find. :)
Multiply 14 by the denominator of the fraction.
14 • 7 = 98
Then add it to the numerator.
98 + 2 = 100
Your answer is 100/7
