Motorcycle Odometer
Knightmare was riding his Harley on a fairly long trip. He glanced at the odometer and noticed the mileage to be 15,951 (reading the same forwards and backwards). As he cruised down the highway, he thought ... I bet that won't happen again for quite a while. Exactly 2 hours later, he glanced at the odometer again and another palindromic mileage was dispayed.
How fast was the Harley going during those two hours?

55 mph
next palindromic milage is 16061 (110 miles more)
110 miles / 2 hrs = 55mph
Suppose he noted the mileage was 134050431 and then noted exactly one week later it was the next palindromic mileage.
How fast was his average speed over those 7 days?
Next palindroic mileage is 134060431 => 10000 miles in the week => 59.52... mph.
I didn't know that Harley made couches.
What's a Harley Davidson? For the sake of the question, I have assumed it to be a mode of transport, like a motorbike.... but not.
55mph, or s....l....o....w.
Actually, he was going 105 mph. The Odometer displayed 16161 miles. He was in a hurry.
