How many hours did Monica spend listening to Brahms if she spent 5.8 listening to Beethoven and Brahms and 1.8 hours was spent listening to Beethoven?

Answer 1

She spent 5.8 hours total and 1.8 hours of that time was spent listening to Brahms. To find how long she spent listening to Beethoven, subtract 1.8 from 5.8.

5.8 - 1.8 = 4.0.

She spent 4 hours listening to Beethoven.
