Mapping question

[Magnum]

This comes from the PolicePrep practice test, question 12 (2007):

A police officer started at intersection B and then looked for a lost child at the following intersections: F, G and I before returning to intersection B to report. How quickly could this task be accomplished if he had to add 30 secs every time the car made a turn at an intersection?

A-9 minutes B-9 minutes, 30 sec
C-10 minutes D-10 minutes, 30 sec

The answer states B because there's a total of 8 blocks and three turns, but I calculated 4 turns. Isn't backtracking from G back to F considered a turn? In reality, you WOULD have to turn the car around.

Or turn the roof lights on and reverse cautiously, eliminating having to turn around!

that's why it's good to practice with this website. you'll learn all those tricks.
i was confused with this too. yes, for some reason you shouldn't count that one.
