Imagine that all the letters of the alphabet are towns situated on a straight line, with a distance 1 miles between each two neighboring towns. A - (1 mile to) - B - (1 mile to) - C - (1 mile to) .... (1 mile to) - Z. Now, imagine you are jogging in the following interesting pattern:
- you start from A and jog to B, then return back to A
- you continue from A to C, then return back to A
- you do this for each subsequent letter of the alphabet, finishing with a sprint from A to Z and back.
What is the total distance of your jog?
