Hi melanie15,

The Time Activities by Customer Detail report shows the hours worked for the activities with the corresponding amount. Let's go ahead and pull it up:

1. Go to Reports.
2. Type Time Activities by Customer Detail in the search field.
3. Select the Report period and click on Run report.

The Duration column shows the total hours worked. You can also find more customisation options by clicking on the Customise button. 

Saving this custom report would be a great idea. That way, you don't have to repeat the steps above. Then, it can easily be access in the Custom reports tab.
