Given the statement:
Ryan must read 150 pages for school tomorrow. It took him 30 minutes to read the first 20 of the assigned pages.
At the given rate, determine how much additional time will it take him to finish reading.
Solution:
We must first find the unit rate of Ryan in reading books. This can be done by dividing 30 with 20.
= 30 minutes/20 pages
=1.5 minutes per page
Now we need to multiply 1.5 minutes by 130 since he already read 20 pages, and we are asked to find the time it would took to read the remaining pages.
= (130)(1.5minutes)
= 195 minutes
Final answer:
= 195 minutes
