Exercise #1: The weight of water is proportional to its volume. It is known that 50 gallons of
water weigh 417 pounds. Let v be the volume of water in gallons and w be the weight of the water
in pounds.
(a) Find the ratio of the weight of water to its
volume as a unit rate. Write first as a
fraction, then simplify to a decimal.
Include proper units.
(b) Using (a), write an equation that relates v
and w.
