The Old Math. One.

If a train leaves Union Station,

in Chicago, at eight in the morning

carrying three thousand dozen gross

of dark almond bark and travels

the average speed of fifty-seven miles

per hour for one day, then collides

with a train that left San Francisco one day

earlier full of fifteen hundred dozen

bite-sized chocolate puppies, how many

days will the residents of Left Foothills,

Colorado, have to spend in the

high school gym while the

National Guard, the Environmental

Protection Agency, and the local

sheriff’s department remove

the worst bite-sized

bark bits (or the worst

bark-sized bite bits) and

return the area to its former

habitable condition?
