<span>Let's solve how many whole minutes does it take 10 000 viruses to grow to 1 million if their population doubles every 15 minutes.
=> 10 000 x n = 1 000 000
=> 1 000 000 / 10 000 = 100 times
=> 100 times * 15 minutes = 1500 minutes to make 1 million viruses

Answer:
w = 13
Step-by-step explanation:
Using the method of cross- multiplying
• = ⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13
