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 1⁄4the length of a grown whale. The average man is 1⁄17 the length of a blue whale, and 1⁄1,818its 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?

The average blue whale measures 100 feet(30 meters) long and weighs 300,000 pounds(136,000 kilograms).

  • A whale’s head is [tex]\frac{1}{3}[/tex] of the length of its body. So, the length of a whale's head [tex]=(\frac{1}{3}*100)feet = 33.33 feet[/tex] or [tex](\frac{1}{3}*30)meter= 10 meter[/tex]
  • A new baby whale is [tex]\frac{1}{4}[/tex] length of a grown whale. So, the length of a new baby whale [tex]=(\frac{1}{4}*100)feet = 25 feet[/tex] or [tex](\frac{1}{4}*30)meter = 7.5 meter[/tex]
  • The average man is [tex]\frac{1}{17}[/tex] the length of a blue whale. So, the height of the average man [tex]=(\frac{1}{17}*100)feet = 5.88 feet[/tex] or [tex](\frac{1}{17}*30)meter =1.76 meter[/tex]
  • The average man is [tex]\frac{1}{1818}[/tex] the weight of a blue whale. So,  the average man weighs [tex]= (\frac{1}{1818}*300000)pounds= 165.02 pounds[/tex] or [tex]= (\frac{1}{1818}*136000)kilograms= 74.81 kilograms[/tex]
  • A human baby measures [tex]\frac{1}{4}[/tex] of the length of an adult. So, the height of the average human baby [tex]= (\frac{1}{4}*5.88)feet = 1.47 feet[/tex] or [tex]= (\frac{1}{4}*1.76)meter = 0.44 meter [/tex]
