The following facts about the section of the canal over the aqueduct were found on the internet.
- It has a rectangular uniform cross-section.
- It is 300 m in length.
- It holds 1 500 000 litres of water.
- It takes 2 hours to drain the water.
Calculate the number of litres of water that drain from this section of the canal per minute.
You may assume that the water drains from the canal at a constant rate.
You must show all your working. [3]
Give your answer in cm2. [3]
