Question

10 p Jayson reads the first 48 pages of a 480-page book in 3 days. Marcus reads the first 50 pages of a 400-page book in 4 days. Nina reads the first 120 pages of a 600-page book in 5 days. If they continue to read at these rates, who will finish first? *

Answer 1

Jayson:

48pag-------------------->3 days

480pag------------------->x days

$\begin{gathered} \frac{48}{480}=\frac{3}{x} \\ x=\frac{480\times3}{48}=30da_{}ys \end{gathered}$

Marcus:

50pag---------------------->4 days

400pag--------------------> x days

$\begin{gathered} \frac{50}{400}=\frac{4}{x} \\ x=\frac{400\times4}{50}=32days \end{gathered}$

Nina:

120pag------------------------->5days

600pag------------------------->xdays

$\begin{gathered} \frac{120}{600}=\frac{5}{x} \\ x=\frac{600\times5}{120}=25days \end{gathered}$

Nina will finish first in 25 days
