Step-by-Step Analysis of Weekly Reading Schedule

Understanding the Context

Today is Monday, and the analyst begins her week with a focused yet realistic reading plan:

Weekend boost (at 50% increased pace): Read 50% more per session on Saturday and Sunday

Let’s break down her weekly reading capacity:

Daily Reading Breakdown

5A science policy analyst must review 450 pages of a climate science report. She reads 30 pages in the morning and 15 pages each afternoon. However, on weekends, she reads 50% more per session. If today is a Monday and she must finish reviewing on Sunday, how many pages does she need to read on Sunday afternoon to complete the task?

Key Insights

Morning (Mon–Fri):
30 pages/hr × 1 hour = 30 pages
→ Mon: 30 pages, Tue: 30 pages, Wed: 30, Thu: 30, Fri: 30 → 150 pages total
Afternoon (Mon–Fri):
15 pages/hr × 1 hour = 15 pages
→ Same schedule: Tue–Fri: 15 pages/day → 60 pages (Mon already counted morning)
Total daily (Mon–Fri): 45 pages (30 morning + 15 afternoon) → 5×45 = 225 pages over weekdays
Weekend (Saturday & Sunday – 50% more reading):
Morning and afternoon sessions still cost one hour each.
On weekends, her pace increases by 50%, so:
- Morning: 30 pages × 1.5 = 45 pages
- Afternoon: 15 pages × 1.5 = 22.5 pages
  Total per weekend day: 45 + 22.5 = 67.5 pages/day
  → Sat: 67.5 pages, Sun: 67.5 pages → Total weekend: 135 pages

Weekly Total Without Sunday Afternoon Reading

Total pages read from Monday to Saturday:
150 (weekdays) + 135 (Sat & Sun) = 285 pages

Final Thoughts

But the full report is 450 pages, so:

Remaining pages to review on Sunday afternoon:
450 – 285 = 165 pages

However, the question specifically asks: How many pages must she read on Sunday afternoon—assuming she prioritizes finishing on Sunday?

Since she already reads 67.5 pages in the morning and another 67.5 in the afternoon, totaling 135 pages on Sunday, she already finishes more than the remaining pages. But to answer precisely and reinforce the full workflow:

Final Calculation: Required Sunday Afternoon Read

Pages read Sunday morning: 67.5
Pages read Sunday afternoon (before finishing): 67.5
Total by end of Sunday afternoon: 135 pages
But she only needs 165 more to complete 450

To correctly clarify the core question — how many pages remain and must be read on Sunday — the remaining unread content is 165 pages, not the full weekend reading. Given the puzzle’s framing, it’s most logical to assume she continues her rhythmic weekend schedule and must read the remainder on Sunday afternoon to complete the 450-page review.

Thus, she needs to read 165 pages on Sunday afternoon, assuming her consistent pace.
