Question

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day. Which expression, when evaluated, results in the correct units and numerical value? Which expression converts 100 inches per minute to feet per minute? Katrina drinks 0.5 gallons of water per day. Which expression shows how to find the number of cups of water she drinks in a week? There are 16 cups in a gallon.

Answer 1

0.109589 millimeters per day.

Explanation:

10 mm = 1 cm

4 cm = 4 × 10

= 40 mm

365 days = 1 year

rate to millimeters per day = 40 mm in 365 days

= 40/365 mm/day

= 8/73 mm/day

or = 0.109589 mm/day.

Rate to millimeters per day = 0.109589 millimeters per day.
