   2) 800 fire­fight­ers (80 sta­tions x 10 in each)

   3) 5,000 trees

   Again, the key here is to try, plan the steps towards the solu­tion, and do the men­tal calculations.That’s the brain exercise.

   Answers:

   1. Around 150,000. Ele­phant: 4,000 kg on aver­age; mouse is 25 grams.

   2. Around 350 fire­fight­ers on duty on any giv­en day, out of a pool of 1700 fire­fight­ing and emer­gency med­ical field personnel 

   3. “There are over 26,000 trees of approx­i­mate­ly 175 species in the Park.” More infor­ma­tion at http://www.centralparknyc.org/17613/4604933

   Im aus­tralian so i have no idea about those amer­i­can-based questions.
