A (for the whole $290$ pages) $\text{= 14.5 days}$
A (for the $180$-page portion) $\text{= 9 days}$

#### Explanation:

A (for the whole $290$ pages)

$= \text{book length"/"read speed}$

$= \frac{b l}{r s}$

$= \frac{290}{20}$

$= 14.5$

$\text{= 14.5 days}$

A (for the $180$ page portion)

$= \text{book length"/"read speed}$

$= \frac{b l}{r s}$

$= \frac{180}{20}$

$= 9$

$\text{= 9 days}$
