Answer:

Correct answer:  t = 10 seconds

Step-by-step explanation:

Given:

V₁ = 12 ft/s , V₂ = 10 ft/s  initial distance d = 20 ft

To the moment  he catches his friend the first skater will have crossed the distance d₁ and the second d₂.

d₁ = d + d₂

d₁ = V₁ · t

d₂ = V₂ · t

when we substitute this into the initial formula we get:

V₁ · t = d + V₂ · t ⇒ d = V₁ · t - V₂ · t  ⇒ d = t (V₁ - V₂) ⇒ t = d / (V₁ - V₂)

t = d / (V₁ - V₂) = 20 / (12 - 10) = 20 / 2 = 10 seconds

t = 10 seconds

=20\ days.

Therefore, it will take him 20 days to read a 300-page book.
