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?

Please explain.

We were just solving it all together in the car and got 650. Who is right?

(25 X 25)+ 25 = 650 miles jogged

Welcome to the Puzzle Marathon, Amy and Ola - we have not seen you here before. Please check new puzzles daily and do not be afraid to make mistakes or pinpoint my mistakes.

Amy is right - 650 is the answer.

Your jog would go as this:

2 miles from A to B and back,

4 miles from A to C and back,

......

50 miles from A to Z and back.

Total distance would be:

2 + 4 + 6 + ... + 50

This sum is (2 + 50) / 2 x 25 = 26 x 25 = 650
