No fours on my odometer (Posted on 2016-06-02) Difficulty: 2 of 5
My lousy car has an odometer without 4s — in every position, the counter advances from 3 directly to 5.
For example, when it read 000039 I drove one mile and watched it roll over to 000050.
Today the odometer reads 002005.

How many miles has the car actually traveled?
