Question

The blue whale is the largest animal living on the earth. The average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). A whale’s head is 1⁄3 of the length of its body. A new baby whale is 1⁄4 the length of a grown whale.

The average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. A human baby measures 1⁄4 of the length of an adult.

Calculate the following information:

How long is a whale’s head?
How long is a new baby whale?
How tall is the average man?
How much does the average man weigh?
How tall is the average human baby?

Answer 1

whales head : 1/3(100) = 100/3 = 33.33 ft or 1/3(30) = 30/3 = 10 meters

new baby whale : 1/4(100) = 100/4 = 25 ft. or 1/4(30) = 30/4 = 7.5 meters

average man height : 1/17(100) = 100/17 = 5.88 ft or 1/17(30) = 30/17 = 1.76 m

average man weight : 1/1818(300000) = 300000/1818 = 165 lbs or 1/1818(136000) = 136000/1818 = 74.81 kilograms

human baby height : 1/4(5.88) = 5.88/4 = 1.47 ft or 1/4(1.76) = 0.44 meters
