Show answer & explanation

Correct answer: C

Key idea: find the web production rate per spider per day.

  • Compute the per-spider daily rate: total webs / (number of spiders × days) = 7 / (7 × 7) = 1/7 web per spider per day.

  • Find time for one spider to make 1 web: time = 1 web ÷ (1/7 web per day) = 7 days.

  • Therefore the answer is 7 days.
