Problem 1:
1 pint of water weighs = 1 pound
1 gallon has = 8 pints
So, 40 gallons have = [tex]40\times8=320[/tex]
Hence, 40 gallons of water weighs 320 pounds.
Problem 2.
Height of Marcie = 0.97 meters
Height of Marcie's father = 1.84 meters
Her father is taller than = [tex]1.84-0.97=0.87[/tex]
So, Marcie's father is 0.87 meters taller than her.
