Question
Water is dripping into a jar at a constant rate. There were 100 milliliters of water in the jar 2 hours ago, and there are 160 milliliters of water in the jar now. At this rate, how many hours from now will there first be 250 milliliters of water in the jar?

First, we need to determine how much the water level in the jar increases per hour.
In the 2 hours since there were 100 milliliters of water in the jar, the level has increased by 60 milliliters (160 ml - 100 ml).
Therefore, the rate of increase is 60 milliliters per 2 hours, or 30 milliliters per hour.
To find out how many hours it will take for there to be 250 milliliters of water in the jar, we can set up the equation:
100 ml + 30 ml/hour x hours = 250 ml
30 ml/hour x hours = 150 ml
hours = 150 ml / 30 ml/hour
hours = 5
Therefore, it will take 5 hours for there to be 250 milliliters of water in the jar.
