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.

From ONTARIO
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.

From WEST VIRGINIA
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.
Sincerely,
