Caroline learns $4$ math concepts in $2$ days. Assuming her rate of learning math stays the same, how many days will it take for her to learn $28$ such math concepts?

• A. $15$
• B. $14$
• C. $16$
• D. $12$

Answer 1

The correct option is B $14$

Time taken to learn 4 math concepts $=2$ days
Time taken to learn one math concep$=2/4=\frac{1}{2}\text{day}$

$=\frac{1}{2}\times 28$
$=14$ days
