• Students Answer Gray Whale Challenge Question #2
"Gaining at a rate of about 1.2 pounds per hour, how much total weight has the calf gained since her arrival at Sea World on January 11?"

From: NEW YORK
This is Claire Modica of the whale team from Mrs. Berger's 5th grade class at the East Hills School in Roslyn, LI. I think that the total weight that the Gray whale calf has gained since her arrival at Sea World on Jan 11th, gaining at a rate of about 1.2 lbs/hr is 1,123.2 lbs. There were 39 days since Jan.11 and since I wrote this, Feb.19th. At 24 hrs. per day, I multiplied 24 x 1.2 and got 28.8. I then multiplied 28.8 x 39 and got 1,123.2.

Dear Journey North,
Cameron Keeney and Emma Lindsey-Hunter figured out that from Jan. 11th to Feb. 25th was 34 days. We then multiplied 34 x 24 hrs = 816. Finally, we multiplied 816 x 1.2 = 979.2 pounds. Wow! that is almost unbelievable.

My fifth grade class came up with this answer to Challenge Question #1: If the starting time was at 12:00 AM on January 12th and we calculated JJ's weight until February 26th at 12:00 AM, then we have 45 days at 28.8 pounds per day which brings her total weight gain to 1296 pounds. Thanks! My kids really had fun figuring this out.

Jennifer from Ferrisburgh Central School, Ferrisburgh, VT figures that the baby calf gained 1065.6 pounds in the 37 days from when the calf came to Sea World to the day the report was posted. Jennifer multiplied 24 hours with the 37 days and then multiplied that by 1.2 to get the answer.
