## Main Question or Discussion Point

I'm confused on how to solve this problem effectively. I have solved it using my own "wierd" way. I will post my solution but please post others that may be more understandable. Thanks.

Problem: Mr. Jacobs can correct 150 quizzes in 50 minutes. His student aide can correct 150 quizzes in 75 minutes. Working together, how many minutes will it take them to correct 150 quizzes?

My solution:

150q/50m = 15/5=3x

150q/75m= 2x

2x+3x=5x=150

x=30 ..lol
