I would love to understand how to solve this problem: In the first week, Judy read for 15 minutes each night before going to sleep. In the second week, she read a total of 100 pages. If she can read 2 pages per 1.5 minutes, how many pages did she read in two weeks?
Can you explain?
Every night, Judy reads 15 minutes/1.5 minutes = 10 sets of 2 pages.
So, she read 10 x 2 = 20 pages every night in the first week.
In the first week, she reads a total of 20 x 7 = 140 pages.
Therefore, she read a total of 140 + 100 = 240 pages in two weeks.
