How much to pay the baby sitter

Shuroug

This will be the first payment, I asked her how much it will be for the past week? She replied $10 per hour.

The thing is, I don't know how to calculate it.

She pick up my son from the daycare where she works to my apartment and each time we meet in the entrance.

Please help me calculate 🤷🏻‍♀️ I don't want to under pay her, it is my first time.

She dropped him to the apartment 3 times, and the driving distance is 13 minutes.

Thank you for your help.
