Fourth graders from Ferrisburgh first wanted to know how many seconds it
would take to cross the Gulf of Mexico. We divided 4 million by 75 and
got 53,333.33 seconds. Then we divided the seconds by 60 to get the
minutes. That was 888.88 minutes. Divide the minutes by 60 and you get
14.18 hours. So, we know that it would take over 14 hours to cross the
Gulf of Mexico.

The Hummingbird takes 14.8 hours to cross the Gulf of Mexico.

The typical trip across the Gulf of Mexico for a Hummingbird is 14.81 hours.
The way I got this answer was I knew it beats its wings at a rate of 75
times per second and that there was 60 seconds in 1 minute, and 60 minutes
in 1 hour. So I multiplied 60 x 60 = 3,600. There are 3,600 seconds per
hour. Then I multiplied 3,600 x 75 = 270,000. Next, I knew that the
hummingbird beats its wing 4 million times while crossing the Gulf of
Mexico. Then I divided 270,000 into 4 million and came up with the answer
of 14.81 hours per trip.

Dear Journey North,
We are a third grade class at Kanawha Elementary School. We would
like to respond to Challenge Question #2. We multiplied 60 seconds times 60
minutes. It equalled 3600. Then we multiplied 75 wing beats per second of
the hummingbird and multiplied 3600 times 75 and got 270,000. We then
divided 270,000 into 4,000,000 and our answer was 14.81 or rounded off to 15
hours to get across the Gulf of Mexico.
