I think the field trip was a pretty good experience, I never walked the bridge before so thanks to this class I had the chance. It was entertaining, the weather was good, we met people there it was fun.
City tech block: 1 minute 26 seconds = 86 seconds
Brooklyn Bridge: 16 minutes 6 seconds= 966
(86/320)=(966/x)
86x=309,120
x=3,595
