The answer is 45 minutes because there are 60 minutes in an hour and you multiply 3/4 by 60 and you get 45.

If you would like to know how many minutes does Hayley spend at her guitar lesson, you can calculate this using the following steps:

1 hour ... 60 minutes
3/4 of an hour = 3/4 * 60 minutes = 45 minutes

The correct result would be 45 minutes.
