Question 1184425
Is it 90 minutes? I want to check my answer.


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 90 minutes.
<pre>NOPE...You and the other person are WRONG. 
She's wrong most times, anyway. So, pay NO ATTENTION to her answer.
Correct answer: {{{highlight_green(matrix(1,7, 80, "minutes,", or, 1, "hour,", 20, minutes))}}}
