Step-by-step explanation:

Step one:

given data

we are told that Mary can read 22 pages in 30 minutes (0.5 hours)

let us find the number of pages per minute she can read

rate= quantity/time

rate= 22/30

rate=0.73 pages per minute

or

rate= 22/0.5

rate= 44 pages per hour

Step two:

Required

time taken to read 100 pages

t= quantity/rate

t=100/0.73

t=136 pages per minute

or

t= 100/44

t=2.3 pages per hour
