She noticed that the people stacking the wood could stack 3/10 of a cord in 2/5 of an hour. (a) Find the unit rate that the water is evaporating at, in terms of inches per hour. (b) If the water evaporates at the rate in (a) for 12 hours, how many inches will evaporate? Express your answer as a mixed number. (a) What is the rate they are stacking the wood in cords per hour?
