Answer:
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
