Answer:
The swimmers splashed 500 hectoliters of water out of the pool.
Explanation:
Let's convert everything to liters so it's simpler:
1 kL = 1,000L
and
1 hL = 100L,
so:
2,500*1000 = 2,500,000
2,500 kL = 2,500,000L
and
24,500*100 = 2,450,000
24,500 hL = 2,450,000L
2,500,000 - 2,450,000 = 50,000L splashed out of the pool.
50,000/100 = 500hL splashed out of the pool.
