"It was 10 am on a sunny weekday"... supply and demand. Take the number of people wanting a ride and divide by the number of drivers available, and in some way that number will be the multiple.
Area will matter (Apparently NYC), but Uber is a gig economy, people use it as a side hustle, so during the day, many of them are probably working another job. Not to mention 2.9 miles in NYC isn't like 2.9 miles in Champaign Illinois, that can be a long ride.
But there are a ton of factors, maybe there was no drivers in the area, maybe everyone was busy, but you still took the ride, so obviously it wasn't too crazy. Uber will continue to charge what they can, but I'm sure the number of available drivers willing to take a fare for that price (The price Uber offers them, not the end user price), will always matter.
Infinitenonblondes in the comments talks about a 3 mile ride, 8 bucks to go there, 60 bucks to leave, because it was a concert. The demand for a ride right after a concert is going to be at record level peaks... of course it's going to go through the roofs.
