Solution

The correct option is D $1800$
Calculate the unit rate of production
Unit rate $= \frac{2400 Packages}{60 mins}$
$= \frac{240}{6}$
$= 40$ packages per minute
So, machine produces $40$ packages per minute.
Since, it produces $40$ packages in a minute.
Hence, in $45$ minutes
total packages produced $= 40 \times 45$
$= 1800$ packages
