Math Problem of the Week - Middle School - Apr. 3, 2022 to Apr. 9, 2022

Middle School: 

Question: Hedy Lamarr was born in 1914. She was a mathematician and inventor - without her, there would be no Wi-Fi or Bluetooth technology! She was also a famous actress. Her first film was release in 1930. Twenty-nine more films and 26 years later, her final film was released. What was the average number of films Hedy Lamarr released each calendar year during her film - making career? (Give your answer as a fraction in lowest terms.)

Answer:  11/9 films

Solution:  Hedy Lamarr released 1 + 29 = 30 films over 27 years—we also have to count the year she started. If we divide the number of films by the number of years, we get 31/27, which is 13/27  as a mixed number and 11/9  films per year when reduced.
