Answer 1

see explanation

Explanation:

The average rate of change is measured as

`(differenceinM)/(changeintime)`

(a)

`(M(16)-M(8))/(16-8)`

=
`(20-10)/(8)`

=
`(10)/(8)` = 1.25 words per minute

(b)

`(M(24)-M(16))/(24-16)`

=
`(25-20)/(8)`

=
`(5)/(8)` = 0.625 words per minute

(c)

`(M(32)-M(24))/(32-24)`

`(25-25)/(8)`

=
`(0)/(8)` = 0
