Answer
We have 4 stages of object's motion:
1- I was at a distance of 40 miles away from my home and remains at this place, which is a coffee shop, for 1 hour.
2- Then I started to move back to my home by my driving my car but it seems that i was moving very fast (at a speed of 60 mi/h) that i did not notice that i passed my home by 20 miles. I wasted 1 hour on this trip and got tired.
3- Then i searched around for a market to take my breakfast. I stayed in this market for 1 hour.
4- Then I started to move back to my home and i played on some classic music and derived slowly (at speed of 10 mi/h). I reached home finally after 2 hours.

The whole trip coasted me 5 hours.
