Type the correct answer in the box. Use numerals instead of words. Ali has hired Mark and Alexis to work for his shipping company. Mark can load a truck with packages in 120 minutes. Alexis can load the same number of packages in 240 minutes.

If Mark and Alexis work together on a particular truck, they can load all of the packages in

minutes.

If Mark and Alexis work together on a particular truck, they can load all of the packages in 90 minutes.

Step-by-step explanation:

Since Ali has hired Mark and Alexis to work for his shipping company, and Mark can load a truck with packages in 120 minutes, while Alexis can load the same number of packages in 240 minutes, to determine how long they can complete a truck between the two, the following calculation must be carried out:

((120 + 240) / 2) / 2 = X

(360/2) / 2 = X

180/2 = X

90 = X

So, if Mark and Alexis work together on a particular truck, they can load all of the packages in 90 minutes.
