Question

You have a special computer that is cooled by a water tank. The water evaporates a little bit

each day but each day the same amount evaporates. At first the level of the water in the
tank is 15 cm. After 2 days have passed it is down to the tank has 14 cm of water. When will
the water run out?

Answer 1

Explanation:

We know that the water level in the tank is 15 cm initially, and after 2 days it has dropped to 14 cm. Therefore, the water level is dropping by 1 cm per day. To find out when the water will run out, we need to know how many days it will take for the water level to drop to 0 cm.

To find this out, we can use the following formula:

Days = (Initial water level - Final water level) / Rate of evaporation per day

Plugging in the values, we get:

Days = (15 - 0) / 1 = 15 days

So, the water will run out in 15 days.
