A (for the whole $290$ pages) $"= 14.5 days"$
A (for the $180$ -page portion) $"= 9 days"$

A (for the whole $290$ pages)

$= "book length"/"read speed"$

$= (bl)/(rs)$

$= 290/20$

$= 14.5$

$"= 14.5 days"$

A (for the $180$ page portion)

$= "book length"/"read speed"$

$= (bl)/(rs)$

$= 180/20$

$= 9$

$"= 9 days"$
