    Nervous Speaker #1 says the word "um" 8 times each minute. Nervous Speaker #2 says the word "um" 10 times each minute. Working together, how many minutes will it take them to say the word "um" 270 times?

    In one minute, Nervous speaker 1 and 2 say "um" 8 + 10 = 18 times per minute.

    We want to know how many minutes it takes for both of them to say 270 "um"s.

    We divide 270/18 to get 15 minutes
