A little confued here... Practice Test 1 ( mapping )

[testing123]

Question : A bike race was travelling through town. It started at intersection A, travelled through intersections G, J and twice through F before finishing at K. What is the shortest amount of time the bike race could have been?

PolicePreps Answer : The bike race could optimally travel A ? B ? F ? J ? K for a time of 12 minutes
Bike time = 2mins

this solution doesn't even seem to add up. a-b (2mins) b-f (2mins) f-j (2mins) j-k (2mins ) = 8 mins??

what am I not seeing here folks? I have to go through F twice.. please enlighten me here...

The only solution I have would be back tracking - which I suppose is acceptable, as it doesn't state otherwise?

Start at A to B (2 mins) B to F (4 mins) F to G (6 mins) G to F (8 mins & twice through F) then F to J (10 mins) J to K (12 mins)

Hope this helps ....

it did thanks.

I never considered back tracking as an option, now, I will remember this for future possibilities
