Mathematics Question Solution
To find out how long it takes Mark and Alexis to load packages together, we need to calculate their combined loading rate. Mark can load a truck in 120 minutes, which means he can load 1/120 of the truck in a minute. Similarly, Alexis can load 1/240 of the truck in a minute. When working together, they can load (1/120 + 1/240) of the truck in a minute. Simplifying this gives us 3/240 or 1/80. Therefore, they can load the entire truck together in 80 minutes.
