Problema Solution
Rudy chose a book with 198 pages. He can read 9 pages in 15 minutes, but he takes a 5 minute break every half hour. If he begins at 8 a.m. What time of day he finish?
Answer provided by our tutors
Every 35 min Rudy reads (30/15)*9 = 18 pages.
Divide 198 with 18 pages to find the number of 35 min periods:
198 : 18 = 11
11 period of 35 min each equals total of 11*35 = 385 min. We need to extract the last 5 min of break, so the total time needed for reading is 385 - 5 = 380 min = 6 hr 20 min.
6 hr 20 min after 8 am is 2:20 pm.
Rudy will finish reading his book at 2:20 pm.
