The depth of the pool is 1.8 meters, the width is 10 meters, and the length is 25 meters.

The depth of the pool is 1.8 meters, the width is 10 meters, and the length is 25 meters. How long will it take to fill the pool 1.5m if 2.5m3 of water flows into the pool every day.

Let’s calculate the area of the base of the pool:

10 * 25 = 250 m2 – pool base area.

Let’s calculate how much of the pool you need to fill:

1.5 * 250 = 375 m3 – the volume of the pool to be filled.

Let’s calculate how long the pool will fill up in minutes:

375: 2.5 = 150 minutes – during this amount of time, the pool will be filled to a height of 1.5 meters.

Let’s express the filling time of the pool in hours and minutes:

1 hour = 60 minutes;

150 minutes = 120 min. + 30 min. = 120: 60 + 30 min. = 2 hours 30 minutes

Answer: the pool will fill up in 2 hours 30 minutes.
