It takes 5 minutes to fill the sink using only the cold water. If both the hot water and the cold water are turned on, it takes 2 minutes to fill the sink. Which is the correct table that can be used to determine x, the time in minutes it takes to fill the sink using only the hot water?
Accepted Solution
A:
The third table is correct.Cold water alone fills 1 sink at a rate of (1 sink)/(5 minutes).Both hot and cold water fills 1 sink at a rate of (1 sink)/(2 minutes).Hot water alone fills 1 sink at a rate of (1 sink)/(x minutes).
