New driver in phoenix

Good afternoon drivers, just started driving for uber and today was my 2nd day doing so. Filling in my downtime as my current full time job is currently in its slow season. I was wondering what the average $ per mile is in the area. My first day was brutal at .40 cents per mile and today was a lot better at .72 cents per mile. Also, how are tippers? Seems like a lot of the working class/elderly tip most of the time but the younger crowd does not. My other side gig was pizza delivery but it was tough to be on a schedule as my other jobs veries in time.
