Answer:

90 Minutes.

Explanation:

The average of 120 and 240 is 180. Then divide that by 2 since there is 2 people, and the answer is 90 minutes.

Baraq

The number of minutes it will take both Mark and Alexis to load all packages is 90 minutes.

Given that Mark can load a truck with packages in 120 minutes and;

Alexis can load the same number of packaged in 240 minutes;

Then we have the average time for both of them as:

Average= (120 + 240) ÷ 2 = 360 ÷ 2 = 180

Given that they were two people involved, then we have 180 ÷ 2 = 90.

Hence, in this case, it is concluded that the correct answer is option B. 90 minutes.
