Paul reads a 40 page book in 30 minutes.
(a) What is Paul's reading rate of pages per miunute?
(b) If he continues to read at the same rate, how many pages will he read in 3.5 hours?
he reads (40 pages)per (30 minutes) or
40/30 pages/min
= 4/3 pages/min.
How many minutes are there in 3.5 hours ?
Multiply that number by 4/3
To find Paul's reading rate of pages per minute, we need to divide the number of pages he reads by the time it takes him.
(a) To find Paul's reading rate in pages per minute, we divide the number of pages he reads (40) by the time it takes him (30 minutes):
Reading rate = Number of pages / Time taken
Reading rate = 40 pages / 30 minutes
Reading rate = 4/3 pages per minute
Therefore, Paul's reading rate is 4/3 (or 1.33) pages per minute.
(b) To find out how many pages Paul will read in 3.5 hours, we first need to convert hours to minutes since we have the reading rate in pages per minute.
There are 60 minutes in 1 hour, so 3.5 hours is equal to 3.5 x 60 = 210 minutes.
Now, we can determine the number of pages Paul will read in 3.5 hours by multiplying his reading rate (1.33 pages per minute) by the time taken (210 minutes):
Number of pages = Reading rate x Time taken
Number of pages = 1.33 pages per minute x 210 minutes
Number of pages = 279.3
Therefore, if Paul continues to read at the same rate, he will read approximately 279 pages in 3.5 hours.
