a.

36 min

c.

18 min
b.

d.

117 min

Answer 1

solve
\[\frac{18}{10}=\frac{x}{65}\] is one way i.e.
\[\frac{time}{page}=\frac{time}{page}\]

Answer 2

another way is to say that 18 pages in 10 minutes is \(18\div 10=1.8\) pages per minute
then \(65\times 1.8\) is your answer

Answer 3

it takes 18 min for 10 pages..
so for 1 page....=18/10
and for 65 pages 18/10 *65
9*13=117 mins
