game was diablo (... that is one hell of a strange encrypted message...) city is Dublin...
I didn't even bother to look at the distance between the two, I just went with the infromation given (690 km avg velocity 460 km/h) and used Dublin to factor in the time difference...
Now that I think about it, I probably should have checked the distance involved, but if I needed to calculate the time it took for said distance, I had no idea what to do with the 690 km.
I didn't think to use it as a ratio like @lukmarcus did XS
@pbock your answer is as well ok. You did not have to calculate ratio as @lukmarcus did. It was my mistake that during riddle preparation I change departure city but I did not update distance between cities. At the end both of you correctly understand the puzzle and I am sure that you knew how to solve it.
09:25 also but got confused a little. The 690km distance delayed me much :\
I did the same. Took given data. My answer was 9.25
